Though not in any way professionally, I have been playing ping pong for over 15 years now. This is the most amazing net I have every played with. The adjustable height works very easily and the adjustable tension works perfectly. The clamps are so strong and much better than any crank down solution I have seen in the past. The clamps are so strong that they align the table back up for us which was out of alignment in the middle by about an inch. Highly recommend.
