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 4 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 5-star perfect if the sides locked.
