I bought this set because my cheap set didn't have a T-handle and I couldn't get the rasp into my rod hole. I was disappointed to find that the rasp diameter in this set was larger than my cheap set and the hole I was trying to plug was very small. Even more disappointing, the insertion tool's handle was bent, as if someone had previously hit it with a hammer. The shank of the insertion tool was also bent. At least they offer a spare insert tool in the kit. So if a bent one fails, I'm still in business. It would be nice to find interchangeable tools that could be used with these grips, but with a smaller diameter (and possibly smaller size). Finally, the case itself is decent, but I'm not sure the single plastic clasp will hold up over time and I tend to put a large rubber band around the case to prevent it from accidentally opening. I think for personal use this set will last a long time.
