Things I liked: I was able to repair my air rifle with this kit, thereby taking a piece of junk and restoring it into a useful rifle. Stacey (your support person) was very knowledgable and helpful, and her support and availablility made all the difference. I had to call 3 times with questions, to which she gave the answers that enabled me to complete the project.
Things I would have changed: The instructions that came with the kit were minimal. The schematic of the gun could be clearer (larger, better picture). The total cost was $38 (including shipping). If it would have cost more than that, it might almost not pay to do the repair.
What others should know: I did this repair over about 5 days. Each day I set a goal: Getting the rifle apart, figuring out how the parts should go back, chatting it up with Stacey to see if I got it right, then finally reassembling the gun. This was a first time repair for me, and like many other things, once you know how, it isn't so bad!
