I've been using this for about 3 months now and it still works like a charm.
The only thing I can say bad about it is that the Pic doesn't line up well when you go to put it back. The whole doesn't guide you very well and so you get frustrated with it and try the other side only to find out you had the correct side to begin with. My solution was to take my bat with spikes and dig a little circle in the wood to indicate that this is the side with the hole. Makes it a bit less frustrating. But for real a good product.
