My new edger
Style: 9" 2T Cutting Blade
I love this edger, I attached it to a Kobalt 24V trimmer with detachable head. It took me a minute to remember how to use an edger with a steel blade after I have been using a string edger for the last five years. The weight is liter than the battery/motor pack. The design and functionality is amazing, I love the adjustability of the depth control system. This thing is super easy to use, loosened one bolt, slide on the attachment align the silver push button and tighten the one bolt by hand and go to work. The durability is yet to be determined, it well made. I like that the right side is open faced which means less chance of clogging up the blade. I am very happy with this purchase and I believe it is a great value for the money

Made it through the first season
Style: 9" 2T Cutting Blade
Product value compared to name brands not to bad so for. Not sure I'd use it for contract work, but great for homeowner use. Engine seems to have an odd burning smell, but performs good (yes I have the correct oil/gas mix ratio which is 50:1). This is very similar to the Stihl models, aluminum shaft tubing on the attachments appear to be slightly thinner than Stihl, but they perform fine. So far it's been a great value for all the attachments you get in the kit. Definitely like the angle capability of the hedge trimmer and ease of changing out the attachments. Chain saw blade did dull fairly quick, but expected that based on it's size. Jury still out on longevity.

Edger Does Not Fit The 52CC Trimmer
Style: 9" 2T Cutting Blade
Might be a great cutter head?? I purchased the 52cc trimmer and edger as a package, however the edger does not fit the trimmer??? Therefore, it is useless... Will see if it fits my 25cc trimmer and maybe change the review... They should tell people in the description that their edger will not work with the 52cc trimmer....

Cut edges like a pro
Style: 9" 2T Cutting Blade
Better, much better than the OEM yellow and black brand. This has an all metal guard and the blade does not bind when it comes into contact with concrete. I have used it all summer for edging two commercial properties and my own lawn, it’s still turning and cutting with ease. Being all metal adds weight but the trade off over fragile plastic is worth the durability.
