Review on High-quality Heavy Duty Suction Cups for Screen Repair - Compatible with iPad, MacBook, iPhone, Samsung, and More by Marco Gavi

I didn't expect much from you. I needed something to help me remove a stuck corrector plate from an old Celestron C8 telescope. The corrector plate is a fairly thick glass lens on the front of this type of telescope. But these suction cups are absolutely not for sale. But what the hell. The only other option was to use a butter knife or similar, at the risk of chipping or breaking the lens. I really didn't expect them to work. The first few tries they popped out and the lens didn't move. On the third try, the lens popped out and luckily stayed securely attached to the suction cups. Problem solved. If I never use them again I still think they are a good buy.
