Even though I only do small batches, I decided to get this floor corker instead of a hand corker. I am very impressed with the quality, especially for the price. Assembly is just one screw to for the feet. I used it for 20 bottles (375 ml) with #9 synthetic corks. Soaking the corks doesn't seem to do anything special (plastic doesn't absorb water), but soaking or just dipping them in water resulted in a slightly deeper position in the bottle. Once you get the depth set, use a bit of blue Loctite thread locker to keep the thumbwheel from moving. If you are using half bottles, you need to use a soup can or something to between the pad and the bottle. I needed to wipe some grease on the rod that holds the pad. I suggest setting the bottle in place before the cork, so you can see that the bottle is aligned properly. BOTTOM LINE: I am very happy that I bought this.
