I bought them for my dad and son for christmas 2 years ago... My wife thinks I'm nuts! The range is very short like 1m or less and for tough guys you need to get close to finnish them off, my dog loves it when I wound a blowie so she can finnish it off, yum salted flies,
I also bought knock offs from ebay, they are not finnished as well and didn't have the laser sight option. Oh did I mention the laser sight it is a must have in my opinion.
Use coarse cooking salt not the saxa in the squeeze bottle.
