Four nylon loop straps arrived quickly and easily and attached securely to my Fitbit Charge 4. The straps are overall comfortable and attractive. Well, at least the dark ones are attractive. The "pink" color looks a bit "off" but otherwise looks ok. (I gifted it to my wife.) I've been wearing the straps for a little over a day, but the strap I'm wearing now seems strong enough. My only real (minor) complaint is that the strap is a bit tight around my not-so-large hand when turning the tracker on or off, but just a little. Also, I was concerned that the nylon fabric might snag on random things around me during my normal activities, but so far this hasn't happened. If the nylon frays or tangles over time I will update this review. Also, I haven't exposed the bands to water yet, so I don't know how well they will hold up. Otherwise so far so good!
