TFY Security hand strap for cell phones FITS my Samsung Galaxy S5 phone perfectly even with the protective case on it. I cant live without this strap on my phone!! It allows me to stop worrying about dropping my phone & to more fully enjoy using it now while texting, emailing, surfing & FacebookingThe TFY strap is made of stretchy high quality material but it does not stretch out or become misshapen. It retains shape & snaps back into place even after holding it for hours outta place.This handy cool essential strap allows me to wear my phone on my hand or on the back of my wrist quickly & securely out of the way when i need to use my hands for other tasks. I also slip knotted a stylus w a stringed loop on it thru an open end of a hook so i wouldnt lose it ever again. U could also insert a slim small clip on carabiner thru a hook due to its open design but i havent tried it yet. Likewise u could insert a lanyard thru the ring on it to wear as a neck holder. The hooks are rubber coated & very sturdy, not flimsy or easily bent. My phone never falls out of it.The TFY strap is superslim & not bulky so my phone still fits snuggly in its wristlet even with the strap still in place. Dunno how I EVER lived without this wonderful invention. They also offer a Tablet strap which fits my 10.1" Samsung Galaxy Tab 4 tablet perfectly.UPDATE after 1 year: TFY phone strap is still working like a champ. Not stretched out or weakened at all. I use it 24/7. LUV this phone strap AND my TFY Tablet holder strap as well. Way to go guys!
