Customer Product Reviews

Rated 4.5 out of 5★ by 34reviewers.
Rated 5 out of 5★ by It is a very good edger/trimmer except it uses a lot of line when used. I have another one by the same company that has double string line and it works a lot better. 08/23/2011
Rated 5 out of 5★ by Exactly what I wanted Just used it for the first time. The trimmer is lightweight, converts easily from trimmer to edger, and best of all is instant on when you hit the switch - no more endless yanking to get the trimmer started! The handle has a clever design that prevents the power cord from becoming unplugged while in use. I consider the disadvantage of dragging a power cord around very small compared to the weight of a gas trimmer and the usually difficulty you have cranking them. 10/23/2011
Rated 5 out of 5★ by Very powerful for an electric trimmer This trimmer works great, it seems so much more powerful than my prior trimmer. I had no problems with the auto feed. 08/17/2011
Rated 4 out of 5★ by Good weedeater, easy to work 03/24/2012
Rated 5 out of 5★ by This was purchased to replace A 15" trimmer which was too heavy for my 75 year old wife. She has only used it once,so far. She finds it easy to use and lightweight. I had previously bought her an Easter outfit. A hoe and a rake. 10/14/2011
Rated 3 out of 5★ by Easy to use, but ... This item seemed pretty easy to use. This item DOES NOT have a cord at all, this needs to be plugged into a wall in order to use... so you have to buy a very long extention cord to use this. I figured there would be at least something small hanging off of it to plug into an extention cord, NOPE! Also, the cord, string whatever you want to call it does not last long, we went through a whole spool "whacking" our yard which took not even 10 minutes. So this may be cheap, but all your money will go into buying a long expensive extention cord and a spool of "whacking" wire. 09/20/2011
Rated 5 out of 5★ by Very useful tool This trimmer/edger is amazing, given its price. The automatic feed system is also awesome. In addition, the replacing spools are also carried by Walmart and are inexpensive. Be advised: it is on the short side. I am 5'7" and its' O.K. but for taller people it could be a matter of concern. Anyway, highly recommended. 02/15/2013
Rated 4 out of 5★ by Works great Easy to use, the string has lasted, it gets thick plants, not much vibration, lightweight. Good value.Only problem, It is not a good choice for us short folks. I really like the product, and could work for a long time, were I able to use it more comfortably. Next one will have an adjustable handle (if they exist). I am fully satisfied with its workings. Easy to clean, works great, but I just can't get comfortable with the length of the stem. The cord kept coming out (a three prong plug would help, but I strung the cord through the handle once, and problem solved. Sure wish it worked a bit better fpr 5 fotters. Having trouble learning how to edge. It is a good product with a good price. 07/03/2014
