The 25 fits for like a US size 10. I was looking for a sturdy craft ?non elastic? string - good purchase. All in all this isn?t a bad cloths rack and if used for light cloths would probably work pretty well. But I find comfort in that because a couple times I pulled out my earbud and the thing got stuck in my ear. Still havent been able to test out the microphone feature because I have not purchased a microphone but Im sure if I get a good microphone it will work great. I looked at like 3 dozen heated towel warmers before selecting this one. These new foam ones were exactly what I had been hoping for. -----------Update 1:My relative is still using the phone and it?s performing quite well and as intended, it?s also getting regular updates and the charging time seems to be impressing my relative every time they charge their battery. After seeing many other brands, the only reason hyperx made them is to look different. The X800M2 seems to be a dream player on paper - relatively inexpensive, support for Dolby Vision, nice build quality.
