almost perfect but sides need to lock in place [SEP] i like this lamp the design really helps when i am doing dual forms with polygel it is really easy for me to get both hands underneath to hold the form no more air bubbles i like that the sides fold down the reason i gave stars is that there is a minor but annoying design flaw the sides don t lock when they are in the open position so they want to collapse once stable this works great but it would be star perfect if the sides locked
