Query: I hate this saw

I don't know how much I can say this. I've had this saw for two years now. Do yourself a favor and don't buy this saw. Here's why:1. The chain is either too tight or it is IMPOSSIBLE to prevent in from falling off. You cut 6 or 7 cuts, put the chain on again, and it falls off again. F R U S T R A T I N G!2. The gas cap swells and is IMPOSSIBLE to get on correctly after a couple of years. Google it. you'll see all sorts of people who have the same problem. You have to use a rotary tool to sand down the cap to get in on. Awesome.Every time I use it I want to throw it across the yard. Other than that, it's fine.
