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

These were purchased to make it easier to remove the protective glass from a 27" iMac. The suction power was way better than I expected and it made the whole repair that much better. It should be noted that the listing says "6 packs" which is not the best description. It's actually "6 pieces" which includes 2 suction cups, two blue levers, a black long lever and a cloth. When you say "6 packs" it sounds like you're sucking 6 times, which actually isn't the case. Be aware of this.
