I felt like posting my experience with one of the newest tool offerings from EGO. Above picture is my current setup in the garage. Leaf blower, hedge trimmer, edger on the new power head, and 15" string trimmer. I chose to get the dedicated string trimmer since the kit it came in was the same price as the string trimmer attachment for the new power head and a separate battery. I'd rather leave the edger attached full time than swap ends back and back.
Anywho, the edger works perfectly. The one thing that would make it better is if the metal guide to keep it against the edge of the concrete had a roller wheel. Sometimes if you let the edger rock too far forward the metal bracket stops you in your tracks when it touches the concrete. Easily dealt with though. I will say that the overall length of the edger and string trimmer definitely requires a 2.0 or 2.5 Amp Hr battery due to the balance. I bought a string trimmer kit that came with the 5.0 and fuggetaboutit.
In fact, I'm so impressed with these tools and the 56V technology that you should know on my 1/3 acre lot with lots of flower beds, I can do all my edging, string trimming, and leaf blowing on a 2.0 battery and still have juice to trim some hedges if needed. I really don't need the 5.0 battery unless I invest in a lawnmower or snow blower. And at this point I'm more likely to buy a zero-turn. Get on it EGO!
Thanks for great products.
