Overall, I feel this is a good product. The design is sold and it is constructed from decent materials (No-Plastic). The only fault that I can see with the device is that they seem to stick some times on the recoil. My suggestion to the manufacturer would be to work on the spring mechanism that opens the strippers back up other wise you can not call them automatic. I have to keep taping them against something for them to re-open. Even with this small fault they are the best strippers I have found on the market.
