This just didn’t stick well at all. I bought it to replace the ring on my phone case that came off, which happens all the time. I specifically chose this style because I had one from a discount store before & I loved it & it worked very well. What I really like is that it’s round. Many phone rings are flat on the sides &/or have a weird shape that’s not ergonomic or comfortable on your finger. Other phone rings are also made of metal, which is good for jewelry that fits snugly but awful for something that you’re constantly slipping on & off your finger. (Or if you’re like me, using it as a holder almost non-stop). The material is very comfortable because it’s smooth & pliable.Unfortunately, unlike the other one I had, this one didn’t adhere well at all. The adhesive came un-stuck almost immediately, like not even 36 hours later! Since I just have a cheap novelty case that I bought in Harlem on 125th St, I went ahead & super-glued the thing to the case. Too bad the original adhesive was just a thin layer that I should have removed before using the super glue because THAT ended up eventually peeling away from the super glue! I re-glued it but I was disillusioned, especially when one of the rings came off. The base is actually really stuck on quite well now & the one ring that’s left seems sturdy. Of course it’s unusable on the car vent, which is actually a bummer on the few occasions that I drive. Oh, well, I still have the other one from the 2-pack. But I shouldn’t have all these issues. The adhesive should be much stronger & longer-lasting & the rings should be sturdier.
