I've never used an edge trimmer before of any kind, so this is new to me. For the first time in my life I have to do this myself, so it's been a learning experience. I spent time researching what kind to buy, deciding on an electric model over a battery or gas-powered one to save myself hassle. This particular Weed Eater has been sturdy and reliable - I have no complaints on its performance. It was amazingly easy to assemble and operate. One of the things I really like about this is the replacement cartridges for the string - it's simple and easy to just pop the old cartridge out and pop the new one in. The only drawback to electricity of course is keeping the cord out of the way at all times, but that's less of a hassle than gas, and requires no replacement like a battery. Its cutting ability more than meets my needs. I only have a small area needing trimming, and using this has been more than sufficient for my grass, weeds and small brush around my house. My only minor complaint is its weight; it's not overly heavy, but it's nice to have the adjustable handle so I can hold it with both hands to balance the weight and control the movement like I want. Making it more lightweight would be the only thing that would make this better, but I'm sure that would mean cutting back on engine power, which I wouldn't want.
