I used these as gifts for some friends. I engraved their kids hand writing on it along with their names and they loved it.

This stainless steel tumbler engraved smoothly, with further detailed notice, the coating on it was evenly distributed, the screws were in tact very well, not even remotely close to be stripped or anything, I love that it came with the screwdriver to remove the handle, it made the job alot easier, everything was packaged nicely, very happy with my selection/purchase.
