Rated 1 out of 5 by from Very disappointed I bought the Troy-Bilt TB4200 cordless trimmer a year ago. It worked fine right up until it didn't. One day it was working great and the next day nothing. All the buttons light up when I push the start button but the thing is dead.. Very disappointed. Was expecting better.

Rated 5 out of 5 by from Perfect for a small to medium yard. First off: I hate weedeaters, I hate trimming! Now I don't hate it so much. Bought the whole suite of Core powered products, and the trimmer is the best, and they are all good. Even has plenty of power to trim my extensive ground covers, also does a good job of edging. And best of all, no " maybe I'll run" gas engine!

Rated 5 out of 5 by from Wonderful power and performance My experience with Troy-Bilt has been fabulous... being a native of Troy, NY( origan of the Troy-Bilt Co), now living in Michigan... I have used your equipment from day one. I now use your latest “CORE” line and find that you latest equipment is wonderful, easy to use, quiet and has a long battery life. I have a little over 1/2 acre to trim and blow. It takes me a little over 45 minutes to trim and about another 15 minutes with the blower, and I still have enough power left with the 40Aph battery to finish my driveways, and still have 50% power left. Thank you for all the years of service with Troy-Bilt... I would also like to complement your Customer Service...whenever I’ve called I’ve always been treated with courtesy and genuine care. I will continue you use Troy-Bilt products as long as I’m able. Thank you for great products that your Company has produced over the years... from a VERY HAPPY Troy, NY Native.

Rated 5 out of 5 by from great trimmer, quiet and powerful Have had this for a few years now. I love it. Have another Core trimmer, and I like the quiet. The power remains more than adequate for me. The weight is good for me as well. Overall excellent trimmer.

Rated 4 out of 5 by from Powerful and Reliable I’ve had the TB4200 for over a year and it has never let me down. I really like how the power automatically increases when the trimming gets more challenging based of the thickness of the vegetation. The battery charges quickly which is great! The only reason I gave it 4 stars is because removal of the battery is difficult to remove to charge. There is a button to release it but it requires something to pry it as well. It’s quite distracting but I love this trimmer because of its incredible power.

Rated 1 out of 5 by from never again When I bought this I was happy about it, but then it came time to order more string. seems that is is almost always on back order. Once I was able to get some I bought a lot. then the Elite Cutting Head Assembly cracked. I tried to get a new one and guess what...you are right it is on back order until the end of next month. I will not let anyone I know buy this and I will not be buying anymore Troy built Products.

Rated 5 out of 5 by from Best Trimmer I ever owned!!!!!! This trimmer is very durable and easy to load with string line. The boost power feature is great for more dense weed growth and it clears the weeds along the fence line and around buildings on the property very easily and without much effort at all; just like a hot knife through butter. I have a few other string trimmers by other manufacturers but this is my one go to string trimmer that I prefer to use.
