I bought my electric not out of desire to be clean or anything. It was just I was tired of keeping a mix of fuels around, then I got one that was just straight gas and it was crazy heavy. They were a pain to get started and I hated turning them off to restring and then having a hard time getting it started again. For me it was just ease of use. I walk out and hit a button and it comes on, it isn’t as a heavy, I don’t have to keep different fuel for it and it just flat gets the job done.
My biggest concern was if I could do my entire yard on a charge. The answer is no. However, it charges fast enough that I can do the front yard, mow and then do the back yard.
