We disagree with the naysayers. Patient use of the suction cup worked for us. The iFixit one didn't do it (it looked a bit deformed out of the box. But a random kids toy worked fine. Nothing fancy. Don't rush. Use an exacto as it starts to come up to slide in to the crevice. After that, works pretty well.
We got this to work. Some patience required, but absolutely doable. Our new iFixit suction cup did nothing, but a random one around the house worked fine. Just be patient and work it gently up, this use an opening tool or exacto blade to get into the seem once it comes up. Really quite doable. I'm glad I didn't spend 25 bucks on the fancy tool (a must for repeat use, I'm sure). But don't be deterred by the negatives above. Just go slow.
