Fitcent Arm Sleeve Heart Rate Monitor Accessories for Whoop 5.0 ONE+Peak/Whoop MG Life/Whoop 4.0, Bicep Wear for Whoop 5.0 Whoop 4.0 Fitness Tracker (L)

Good quality! Definitely a great knock off of the orginal arm band.. however, size DOWN

The reviews that this thing fit OK at the start, but after only wear on it four times, it already slips off my arm. Not sure if the solution is to buy a size smaller than you’re supposed to, but it’s not worth the money at all.

Runs big

Velcro came off after the third use, but it still works without it

Ok but prone to stretching. Works fine under a race for bike jersey but not anything loose fitting.

Nothing link the original arm band, I am a women and it falls down and stretch way to easily.. waste

Worked great but don't hold elastictisity for long

Elasticity did not last long at all and the Velcro fell off after 3 weeks.

I am rather hesitant about supplement products as most of the time I feel like they don’t do much , however with Alpha drive genuinely feel a massive difference in my performance activities & just day to day , I feel much more energised , as for the T levels , I can’t say I feel any different in that regard however I wouldn’t notice if I did , bought 3 times now and can confidently advise anyone to purchase these over other brands as I’ve used ChatGPT to compare the ingredients to other brands and it all leads back to Alpha drive

Broke after 1 wash! Do not buy

Size guide was terrible. I need one, maybe two smaller.
