    Must get it for pain relief

    Just arrived with UPS, you must charge before using, and please read the booklet while charging which explains the unit so you know how to use properly. And you have the warranty included already in the purchase I was told. Had pain for a month. Last night was it, toss turn, pinch nerve. Anyhow, this unit has many programs. Put on the Acu setting and use 15 minutes, awesome. Was able to move my neck no pain. I feel a full nights sleep tonight. Thank you Relux for making a affordable unit.

    Thiis thing is AWESOME!!

    I have had this unit about a week and used it a bunch of times now and just could not be happier. The build quality is good and it came with a remote and instructions, I love that it doesn't require any batteries and is rechargable like a mobile device. And the charge stores for a long time The battery has been great. I have done several treatments on a charge. This seems to have really helped in the short time I've had it. I still wake up very stiff and the muscles around the neck can be very tight for me. Each day has seemed a bit more tolerable. The power of this thing is incredible. Around 1/4 power is all I have needed. Combined multiple modes like acupuncture and heating and they have really helped so far. To me 5 stars for the money paid could not be more pleased.

    Amazing Device

    This unit is great and It is super powerful and versatile. Mine needed a good charge out of the box, but after an hour or two I got my first session in. Just around 10 minutes. Just about level 3 in strength (will be plenty) at a time but it allows all types of message. It really is helping me with some damaged muscles. It fully activates muscle groups with a wide effect and deep contraction. I am sure it will speed healing, relieve daily stress, and more. I have felt it restore some functional movement!

    I recently had a car accident and my therapist suggested a TENS device. I immediately went looking for one, skeptical at first to purchase plus I needed to do some research on the unit before purchasing the unit. It is amazing for the price and mobility. The design and feel of it is awesome, so awesome I almost wanted to do a YouTube review. Don't be a fool like me and suffer in pain waiting, GET IT NOW!!!
