These are very good cuffs. Very happy I found them. No need to pay $500+ these work just the same, if not better
I had difficulty using it , my veins hurt. Need to try again
The cuffs are difficult to put on without the strap sticking to mesh. They should have designed them like the Smart Cuffs where the the strap comes through a loop and pulls back the opposite direction without sticking to mesh. The valve can also be difficult to connect at times. Overall, they get the job done with right amount of pressure.
If you plan on using these for BFR training, these are exactly what to purchase. The pump and gauge are a bit inconsistent, so I would not use this for medical purposes where precision is required.
