Overhyped

Right out of the box these cuffs were very difficult to connect. I got errors once they were connected and when they tried to inflate they failed. Pressing the emergency stop button did absolutely nothing. For 900.00 this product should work flawlessly and the construction of these makes me wonder if they will last a year. A user opens the box gets started and immediately has issues. Not a good first impression and a huge let down after spending so much money. I am considering returning these and going to another brand. I was excited to get these now it’s womp womp. Do better guys.

Works incredibly well

I noticed that this is the brand my Physical Therapist was using so I bought a pair for myself. Nice to have peace of mind that it’s able to adjust to what my body needs as far as the amount of tightness.

After 3 weeks, my left knee is getting less and less achy because my left quad has improved so much over that short period of time. I’m also noticing a very quick progression in strength and size there and when I use the arm bands to do push-ups, both in my arms and in my chest.

This has revolutionized my martial arts training by helping me get past the weak foundation from my knee and has helped majorly with kata and normal everyday techniques.

Because this tech was developed originally in regards to older people, I’ve been able to recommend it to my aging parents to help with some of their muscular problems, to help give them a firmer foundation for everyday life.

Great for people who don’t have the time to get to a gym or don’t have access to heavier weights.

There are lots of pointers and tools on the SmartTools website for exercises and safety.

Thanks SmartTools!

Updated firmware bricked my cuffs

Updated one cuff, plugged in near the others. Worked for a few days now they won’t turn on. Reached out to customer service let’s see what they say - fyi to those thinking about updating

New app version is unusable.

Update is completely unusable. Takes forever to load fails to load client lists gifts for more update issues without there being a new firmware available needs to be fixed ASAP

Great quality cuffs tech need work

Would be 5star easy if app worked. Likes to disconnect while saving sets which I learned to not even do that. Just pay attn to timer and keep track of sets that way. It wouldn’t disconnect during your session. Now it likes to disconnect after saving sets which and then cuff would change color. So now you have to go though whole process again. So tech needs work but overall cuff is made of good quality
