It's pretty good, but i find the pads very hard to fine adjust since it's a bit rattled. For adult capses and beanies it's good, but when it comes to kids capses and hats i really can't adjust the pads to not knock the screen/brim to be pressed outwards and it gives me a bad press on the front and the brim sometimes get deformed.
I'm using it 99% for leatherettes and it works good even without heat from both sides.
I measure the heat pad accurate all over the element, so i'm happy with the purchase and it's great for the price and hobbyists.
