Review on Adjustable Carpenter Cabinets by ChgImposs Woodworking by Scott Channell

I've used these for picture frames and they work well with 45 degree cuts. You can clamp material about 1 inch thick in a vise and it will hold tight. The springs are very strong, and sometimes it can be a little tricky to get both pieces of wood in a vise so the other doesn't slip or pop out. It comes with some extra parts but I have no idea what they are for, spares maybe. ? They come naked in a box, no plastic packaging, no instructions.
