I have had this Plano clamp system for about two years and only really began to use it recently, it was a little fiddly at first to really understand its ways of working but when you begin to understand the process of how to properly use it the results are pretty amazing. Glueing panels is usually always part of a piece that I make so I did invest in this system, I will in time increase it from 3 clamps to 5 but I cannot sing its praises high enough. They are alittle expensive to purchase first time but they do offer a great way to put together a very flat wood panel.
