I was skeptical especially as the velcro adhesive pad that sticks to the phone seemed to just be glue. But after mistakenly sticking it to the wrong spot, I peeled it off, washed it under water, let it dry and it was sticky again. No residue on my phone either. And it is such a strong fastener to a finger that it will transform how I use my phone for texting/web browsing etc. I do not need to worry about dropping it!
Fast delivery considering it is from Singapore (2 weeks). Fully recommended!!
