Looks like you visited Harbor Freight! I do too, on many things. I started with an electric many years ago, & it may have been the same brand, except it was made with Metal. Wasn't as strong as the air guns, & eventually quite hammering. Several years later I found a Mac Tool man, that did repairs. He checked it, & said it was wasn't worth fixing. The hammer assembly was worn out. Parts cost too much. I've stuck with air, & running a Kolbart now. I've seen a lot of guys using the battery powered impacts, both in shops & on the Trail. Haven't seen anybody with electric. Like Any tool, it's life will depend on the amount of use.
