I agree with the first post. I then got their production model and for the money, it has worked very well. We do approximatly 2-3 kitchens a month. For the money and the tool's dependability under production stress, we use several DeWalt spliners including the cordless model. Before setting up dedicated machines to mill my beaded frames together with mortise and tennon joints, I used to use BOTH biscuits and pocket screws.
Biscuits are quite strong but a pain to clamp up.
Pocket screws are quick but have limited strength. Using both produces a strong joint quickly. Just remember to drill for the pocket screws before you slot for the biscuits or you'll get chips in the slots. I tried biscuits and found it to be too time consuming. I went back to my old method using senclamps.
