BGA 45 is rated 2.8 out of 5 by 74.
Rated 1 out of 5 by from very short run-time I have a 1500 sq. ft. driveway and with a full charge, this blower will not clean it when there is only a small amount of debris. Less than 20 mins. run-time.

Rated 5 out of 5 by from Super tool I bought this blower from a local distributor a couple of weeks ago, for my wife since she has trouble getting our heavy duty Stihl gas blower started being petite. It is great not only for her but i use it all the time for small jobs.After giving it a full charge, i found it worked for 15 min straight doing a gravel road at about 80 F today. interesting, it runs at full power all the way until it just stops. I didn't get a warning by it running sort of slow before it just stops! I am okay with that as long as i know it is going to stop after 15 minutes of continuous operation.

Rated 5 out of 5 by from VERY HAPPY I am happily surprised how great this blower is. It is light weight (with Rheumatoid Arthritis lightweight was a must) but still very powerful. It does all we need it to do with ease and quickly. The charger is easy to use and charges quickly and keeps the charge for a long time. We are very happy with this blower!

Rated 4 out of 5 by from Great little tool I don't think the review score matches up with how great this tool is. I think the expectations are probably too high it does a great job of clearing a sidewalk of about 100 ft and I think that's what it's intended for it clears a deck easily enough and walkways and pathways or driveway after you dust it up with sawdust

Rated 1 out of 5 by from Terrible product. Be embarrassed Terrible product. Surprised Stihl would manufacture such a inferior product. Tech supports at Stihl headquarters said he has competitive brand at his house because all Stihl blowers are inferior to competitors

Rated 5 out of 5 by from Love, love, love this blower! I wanted a lightweight blower to use on walkways, decks, and an asphalt driveway, and this model is PERFECT! Hubby has a gas blower for the lawn, but it’s to bulky for me. This Stihl unit is so simple to use and so lightweight, I love it. While it does need to be charged every other time I use it, I’m able to easily clear two 600 sf decks with stairs, a concrete patio, walkway, landings, and stairs down to the dock each time. It’s so simple to charge, it’s not a big deal. I absolutely love this tool.

Rated 4 out of 5 by from Perfect if used as intended Just purchased today. Bright it home, plugged it in to charge, and used it immediately. Was able to test it at the store before I bought it. The power is great unless you think you are going to go out and blow a yard full of foot deep leaves. Cleared two porches, under one porch, the garage and my backyard patio on the first charge. It was not dead at the end but was down to one bar. Cut it off between spots, don't blow aimlessly and be efficient with your time. It does only last probably ten minutes but if you minimize waste, it will do the job just fine. Do not buy this blower thinking you are going to blow your yard full of leaves. It's strong enough to blow some leaves but will need multiple charges.

Rated 5 out of 5 by from A great tool for small jobs I've read several unfavorable reviews about this blower, but my experience with it has been very favorable. I purchased the blower for my wife who uses it to clean of our front sidewalk after I mow. It's light enough and easy enough for her to use, and it has more than enough power to blow grass off of the sidewalk. Some of the unfavorable reviews complained about the length of time one can run the blower on a battery charge. This is an economical light duty blower, and one shouldn't expect it to have the run time of a gas powered unit. My wife has used the blower 5 or 6 times to clean off our 4' X 24' sidewalk, and the charge indicator still shows three lights; that seems very good to me.If you need a blower for small cleaning jobs, the BGA 45 is a blower worth considering.

Rated 3 out of 5 by from Battery only lasts 5 -7 minutes Has decent power but you only get 5-7 min on a full charge
Date published: 2019-05-07
Rated 5 out of 5 by from Very good lightweight blower We wanted a blower that could clear the back deck of leaves, and it needed to be easy to operate and lightweight. This unit certainly fit the requirements; it makes cleaning the deck easy and fast. Now we can enjoy more of our evening time, rather then spend time sweeping off the leaves-we just blow them away. Great value for the money.

Rated 1 out of 5 by from Battery sucks Brand new and the best I get is 7 minutes of battery life. You can't get anything done in 7 minutes. By the time it recharges I've got the rest done with a shovel. Waist of my money.

Rated 4 out of 5 by from Good blower and good value! The BGA 45 is a good blower. I did expect a bit more power, however. Couple of suggestions: 1) After charging the battery and letting it sit, when you first apply power, it would help to show the battery level ... just in case you forgot when you charged it last. 2) While using it, it would help to show the battery level as it declines so that you can plan on how much longer you can use the blower before having to stop and re-charge it.

Rated 1 out of 5 by from This product sucks. Battery lasts less than 10 minutes. Took it back. Seemed like a good idea. Operationally it had enough power to do what I expected for a small blower. The battery lasted less than ten minutes!!! Worthless to clean anything larger than a 40 square foot area!! I took it back to the dealer. Don't even think of buying this unless you have a VERY small area to blow.

Rated 5 out of 5 by from perfect for a large covered patio powerfull enough, battery last for a month of daily short use. and it is so quiet I don't need my headphones. Perfect for what I needed.

Rated 5 out of 5 by from Just what I needed!!!! My husband bought this for me so I wouldn't have to bother unrolling 75 ft. of extension cord. Once I knew it's limitations, I was quite happy with it. It's perfect for clean-up work after he mows the lawn, etc., and the battery lasts long enough to accommodate these kinds of quickie jobs, and my stamina. When I'm finished, I recharge the battery and am ready for the next day's work. Great for a 77-year old woman!!!

Rated 1 out of 5 by from Very limited battery charge I purchased this product as it was from Stihl (love their chain saws) and thought that this would be a good foray into battery powered yard equipment. This blower is very light and rather quiet, but when I first used it, the charge only lasted for about 10 minutes. I thought that perhaps it was only charged for demo purposes and plugged it in to get a full charge. I took it out again the next day and it again died after 10 minutes. That's great if you are cleaning off a city driveway of have a postage stamp sized yard, but it is totally inadequate for a regular sized yard.

Rated 4 out of 5 by from The main thing is lightweight and it is strong for a small motor You could probably blow out for two car garages I don't think you'd use it to blow out a yard though but you could blow out your driveway and your carports and garages and Patio but it does it lasts about 20 minutes

Rated 2 out of 5 by from Need more Love Stihl products. Unfortunately this did not measure up and had to be returned. Battery life seemed to last about 10 minutes. Facing the choice of spending more for a Stihl upgrade or spending less on a comparable competitors model that has a battery life of an additional 10 to 15 minutes....returned the Stihl and kept the Competitors model. Would have loved to keep the Stihl...but....

Rated 1 out of 5 by from disappointed in battery life Battery runs for 10 minutes (at the most on a full charge).Very disappointed regarding run time. I like that it is light and easy to handle. I would not recommend this product to blow leaves and such off a 16x20 deck, or snow off steps! It just does not last long enough.

Rated 5 out of 5 by from PERFECT I purchased this product to replace a perfectly good gas blower. It was difficult for me to start and was heavy. I use this to blow the drive and sidewalks after mowing and trimming and blow the garage floor several days a week. It's not very powerful, but it does the job and is lightweight and doesn't require mixing any fuel or yanking rope to get it to start. I charge it after every use and keep it clean and stored out of any dangers.

Rated 5 out of 5 by from Perfect for job at hand Almost didn't buy this blower after reading reviews.Glad I Did! I need a lightweight blower for my wife for cleaning garage and back patio. Plenty enough power and Battery for both which was main complaint in reviews. I have a stihl gas blower for the yard and fall leaves. Talked to my stihl dealer about power and battery, he told me if I wasn't happy he'd take it back and we could go to a bigger battery powered unit. No need this is perfect!

Rated 4 out of 5 by from Easy handling I really enjoy the ease of using this blower. My garage is always clean now that I have this blower. I was so tired of using a broom. It's so easy to just grab the blower and go! I also use it too clean driveway and sidewalks after mowing. It blows at 85mph, but do wish it was a bit more powerful. I would still recommend this product. I think it's a good value for the price

Rated 5 out of 5 by from perfect tool for my camper I own a fleet of Stihl cordless tools for home and love them all but needed a small cordless blower to use while camping to blow off our patio rug and awning. It works perfect. We like remote camping without electricity and one charge of my BGA45 lasts my entire camping trip. Great tool!

Rated 1 out of 5 by from 9 minute battery life From a full charge this will run for exactly 9 minutes.My dad bought this for me without reading any reviews or doing any research on it.I am extremely annoyed to have to make an hour long drive to give it back to him so he can hopefully be able to return it.Why Stihl thought that putting an integrated Li-Ion battery device on the market with such an unacceptably short run-time is beyond me... they're obviously losing brand loyalty by selling this kind of junk product.

Rated 1 out of 5 by from I'm blue once again The battery doesn't even last 15 minutes. I can't even do my side walk and drive way. I fell for this one. I thought, spend the money, get the name, splurge on yourself for once. Names mean nothing anymore.
