The best one ive had I recommend it for someone thats lookin for a replacement for their trunk rack strap. I have tile surrounding the stove, these are perfect, adhesion is reliable. As long as your pieces fill up the slot to that point, youve got 32 pieces on that side. This is a decent product, but the promotional photo is a bit misleading. No fitting instructions or tips like I just gave you so Im dinging it one star. I have these plugged into my computer at home with the included adapter. Not fancy as touch screen, but conventional button to mute the mic and control sound volume thru the spin switch. Ill post an update if these fail prematurely or if you find this review helpful (yes, I really will! I have several pairs of these in various colors.
