**Will not fit CK17 Flex headlamp without modification** I read this in other reviews before buying so I'm not deducting stars for this. This is a great starter kit, glass cups are too big for aluminum welding unless you want to use a lot of gas. Again, this isn't a problem with the product, but if you want aluminum glass tumblers, buy a different size pack instead to get some smaller glass tumblers. However, this is a decent quality set with lots of detail for the price. With the CK 17 burner, the white rings must be enlarged. I used a small grinder and a drill and it worked great. Wet the o-rings before installing the glass bowls and they will continue to function without pushing the o-rings off the diffuser.
