I am not at all impressed with this resaw guide. I had a difficult time keeping the blade going straight because of the curve on the face. I used it on my first attempt at resawing and immediately removed it. I made another cut without it and it was perfect. However, I am using a blade made for resawing and spent time calibrating the saw. Over all, I am not impressed with Kreg products.
