### ⭐⭐⭐⭐⭐ 







  
  
    Great quality, good color variety, and awesome deal!
  

*by J***J on Reviewed in the United States on January 4, 2018*

I was pretty skeptical when I ordered this set of bands for my Flex 2, but I really wanted more variety than the few colors offered by Fitbit.  After all, if I'm wearing this thing 24/7, I should be able to make it blend with my outfits, right?  I mostly wanted the darker, more subtle colors -- black, dark & light gray, purple, navy -- but I figured the peach one would  might be nice and neutral as well, depending on what I'm wearing.  The brighter ones aren't really my style, but you never know.  I was just worried that these would feel like a cheaper plastic, wouldn't fit as well, or would in some other way be sub-par.  Turns out I had nothing to worry about.The package arrived faster than expected, and honestly, I was immediately surprised by the quality.  These bands look and feel exactly like the "real thing," with no difference in fllexibility or sturdiness.  In fact, the metal clasp piece seems to be an even tighter fit in those little punch holes than my original band, so there's no doubt it will stay securely on my wrist.  They fit so securely that the little added silicone band to fit over the overlapping ends seems almost unnecessary.The variety of colors in this pack is really nice, too, and even the colors similar to those that Fitbit has are different enough that it's worth having both.  My Fitbit Flex 2 came with the lavender wristband, but as you can see from the attached photo, Fitbit's is more of a grayish lavender, while this pack's lavender is brighter and more of a true pastel.  However, even with those small color variations, these bands don't look/feel at all like knock-offs.  The texture and flexibility is the same, the sizing is identical, and even the clasp is metal -- of sufficient quality that my super-sensitive skin hasn't reacted at all to it.  These bands hold the Fitbit pebble just as securely, and the indicator lights glow just as brightly through it.  In fact, the only obvious difference is actually a very subtle one -- the small, barely visible Fitbit logo doesn't appear next to the clasp.If you want to change up your look or make sure your Fitbit Flex 2 matches what you're wearing, this affordable set is an absolute must-have.UPDATE: So I've been wearing these things 24/7  for about 3 months now, and they're still awesome.  None of them have broken, come loose, or shown any soiling or wear.  Definitely one of my better purchases!

    Wristband WITH fastener that’s interchangeable with Fitbit Flex 2 wristband
  

*by M***. on Reviewed in the United States on November 4, 2018*

I was disappointed to find out Fitbit doesn’t sell fasteners for the Flex 2 model. I always need at least two wristbands so I can switch quickly after I swim, rather than take the time to thoroughly dry out the one I was wearing. I lost one and ordered more from Fitbit but they came without fasteners and Fitbit seems to have stopped selling the fastener separately. This company sells almost the identical band and it includes a fastener - one that is interchangeable with the Fitbit model. Now I’m all set for swimming and have new colors to match whatever I’m wearing that day.

    OK, but I can't take the odor
  

*by K***L on Reviewed in the United States on August 28, 2018*

I ordered one of these bands because I needed a new clasp, and it was the cheapest way I could find to order a single clasp. When I got it, I thought, “Hey, the band’s actually pretty nice!” So I tried it out. It’s a little stiffer than the Fitbit brand bands, but it looks nice. The problem was the strong smell that wouldn’t dissipate – an almost floral chemical scent. Maybe it would have finished off-gassing eventually and been usable, but after a day or so I just tossed it. The clasp works fine in a Fitbit brand band – not *quite* as smooth to snap on and off as the real clasp, but not bad for the price difference.
