My signature Fitbit band has broken twice in just over a year. They replaced the first one for free but didn't even want to contact them again about that one, so I looked for other bands. This set is great. Most likely I will use them one by one and not swap colors. Feelings are really pleasant. They went in straight away with no problems. I don't know anything about durability yet, but it seems to be well made. The only difference from the Fitbit strap is that the Free Loop (as it's called) has nothing to hold it in the strap holes. I haven't had any slippage issues, but that's the only real difference. Of course, these groups are worth their money.
