Compex® Performance™ 3.0 Muscle Stimulator with TENS Kit – 6 Programs – Helps facilitate and Improve Muscle Performance

Excelente, la calidad es muy buena realmente

This unit is pure junk for the price being asked. Only reason I will even give it 1 star is because the interface/screen is decent. Don't even buy it on the premise that you can return it because Amazon says it's ineligible for return, after less than 24 hours. So I'm out $150 because I will never use this thing again. I will never buy this brand or from this seller again either. Unless you are planning to jump in the pool with this thing the silicone case is worthless and makes it so much more bulky than it needs to be. Taking it off is a pain. Obviously the first I wanted to do was charge it. First thing that happened was the the flap covering the charging port was such a thin layer of silicone for a hinge that it immediately broke off. Plugging into the charging port was no easy feat either. The plug has to be so perfectly aligned while inserting that I'm afraid of braking the connecter away from the board, if the flap cover was any indication. And speaking of taking the silicone cover off, I wouldn't. The hole around all the ports are so much larger than the connector that you can literally see the light from the display shining through them. So you will definitely get dust and other debris in the unit. The charging cable is the really ancient mini-usb, not usb-c. The connectors are also designed in such a way that you won't have any real luck buying 3rd party accessories like replacement pads. Performance. So lackluster. I have a cheap tens/ems unit from 5 years that runs circles around this thing. You are limited to "modes" and have to select body parts you're working with. So not much room to just slap it on and go. There are 999 levels of intensity, which is insane to me. I barely started to notice something at 250. Slowly cranking up to the max level I felt something, but it was so marginal that I got nothing out of it. I'm not looking for full blown seizure activity, but c'mon, I should feel some kind of contractions here. I tried various body parts, conductive gel, taping down pads to make sure they had full contact with my skin. Nothing. I read through the manual twice thinking I missed something but there's nothing to suggest I have. It only comes with 4 small pads and 2 wide pads. Seems like enough, but the adhesive wears out so quick you will have apply gel for every use or tape them down. The replacement pads aren't exactly cheap either. Don't buy this thing thinking it's going to improve any kind of athletic performance. I'm an athlete and nothing in my research has ever found any clinical study to support improvement in ability with a device like this. So the modes are purely hype - warm up, pre-warm-up, explosive strength, endurance. The unit even says it's targeting fast twitch or slow twitch muslces. Give me a break, show me the unbiased double-blind studies to support all that marketing garbage!

Love it. This is only available in the USA. Unfortunately the pads suggested by Amazon was incompatible. A shame.

It works great!

You're going to think I'm making this up but look at the picture. Look how deep that charge port is. None of the bazillion micro USB cables I still have from previous phones have a skinny or long enough end to reach the port on the board. So, everytime I need to charge this thing, I have to take it apart like this. I've seen pictures of the special Compex cable that supposedly will reach (seen in someone else's review here) but they didn't include one with my unit. Enjoy this wonderfull example of proprietary fast fashion industrial design. I hope you're handy.

I’ve been using item for 20 years now excellent always no problems i would buy the blue tooth one but to expensive

Genial

Came with no charging cable so it’s totally useless after the battery runs down. Customer support was useless. Claimed they were out of replacement charging cables.

Llego super bien, ya lo había utilizado antes y quería uno personal, así que si es una buena inversión

FACIL DE USAR Y MUY EFECTIVO

El producto llegó defectuoso, el cargador no carga y 2 de los circuitos no funcionaron desde el principio y no se puede devolver. Un producto muy caro y llegó defectuoso

Espere un par de semanas para darle uso y subir un buen comentario y la verdad lo recomendó mucho, cuando se sabe utilizar correctamente es una herramienta maravillosa, quede encantada😍😮‍💨
