Works well and rechargeable.

I was excited to purchase the TENS 7000 Rechargeable after reading many positive reviews. However, my excitement was short-lived when the unit failed after just one week of use.The unit worked great at first. I used it to relieve pain in my back and neck. The intensity levels were easy to adjust, and the controls were user-friendly. However, after one week, the screen went blank and the unit would no longer turn on.However, I'm concerned that the failure rate for this unit is high. I read many reviews before purchasing, and many people reported that their units failed after a short period of time. I'm not sure if this is a design flaw or a manufacturing defect, but it's something that potential buyers should be aware of.Overall, I'm disappointed with the TENS 7000 Rechargeable. It's a nice unit when it works, but the failure rate is too high. I would not recommend this unit to anyone unless they are willing to take the risk of it failing.Rating: 0 out of 5 starsPros:Easy to useIntensity levels are easy to adjustCons:Failure rate is highScreen went blank after one weekConclusion:The TENS 7000 Rechargeable is a nice unit, but the failure rate is too high. I would not recommend this unit to anyone unless they are willing to take the risk of it failing.Update: I was sent a replacement and the same problem happened, screen lit but blank and no buttons work. Don't waste your money on these units, they only last about one week and you need a new one, LOL.

Muy bueno el articulo.

Unit works extremely well, when it does work. As numerous other reviews have noted, it does have a particular failure mode-the blue screen of death. BUT.....after reading several of those reviews, I wanted to pass on two fixes that others have identified. Or should I say-temporary fixes, as the blue screen eventually comes back. OR.....just reach out to the customer service number listed in the manual, if you're within the 1 year warranty & they'll take care of you. First-problem description: The unit will all of a sudden show a blank, but lit screen. Pushing the buttons does provide the normal beep. I also found that the TENS stimulation also works, but of course without the screen providing the info on the mode, intensity, etc, its basically useless. So here are the fixes: First one-for those less tech savvy-just leave it turned on until the battery is completely drained. Then charge it back up. Should work fine, until the blue screen issue eventually comes back. Second option-pop open the case, and briefly short the battery terminals. Need to remove the two top screws on the back, then carefully pry the back open starting at the top seam. Turn the unit on so you can confirm when you've properly shorted the two terminals. Use a bent paperclip or something & briefly short the two connections together. Screen should immediately turn off. It should work fine after that. Reassemble & get back to TENS'ing!

At first I wasn't sure how to use this compared to the simple setup I used to use. It turned out to be much more versatile and effective, but there was a little bit of a learning curve I needed to navigate. Design wise, it is much better than the set up where are your terminals are like snap connections in shirts and blue jeans. I learned real quick how those snap connectors are very inconsistent and the pin and sleeve termination for these is so much better and more consistent it is absolutely crucial! The frequency modulator is so much more versatile and effective! I could be sitting, I could be walking around, I could get any type of zap I needed for my muscles! I can see how analog controls could be better than the digital controls, but it's not a big deal pushing a button many times until that button start to fail. I do recommend serious consideration for the analog dial control option.
