All in all this is a good buy for $. I've driven about 300 nails through with just one joint. It appears to be significantly heavier than my comparable Dew**t, but I haven't tested that. In conclusion, I recommend NOT using the little guide provided to change the angle as it is almost useless and written in very poor and confusing English. I had to because I was in the field and basically figured it out myself. However, the guide the seller has on this page is great! I just didn't have access to it at the time.
