4 in 1 - D.I.Y & Tens Unit & EMS & Massage Muscle Stimulator, Dual Channel Therapy Machine for Pain Relief, FDA Cleared Rechargeable Electronic Pulse Massager,with 12pcs Electrode Pads

Absolute life saver, so good I feel as though I’ve been to the osteopath after a session with this. Love it, use it lots, easy to use and you can adjust to suit!

Excellent product, have had sharp pains from my calf muscles up to the top of my right leg. Has suppressed the pain and is also helped to strengthen the leg muscles to reduce discomfort. Pads are good if looked after, couple have lost stickiness. Has good power and excellent battery life

Instructions aren't all that clear especially how to get out of DIY,but works well.

This is an easy device to use , quite a few set programs to allow for pain relief or massage that work very well. The only small problem I have found is that the programs only last for 20 minutes and then you have to restart it , this isn't a big issue though my old one didn't have this problem. Overall I would recommend this item as it works very well.

For those seeking a professional yet home-friendly muscle stimulation and pain relief solution, the Kongzee 4-in-1 stands out as a reliable choice.

This a great item. Works really well and charge last a good few uses. I used this after knee surgery to help with recovery and was really helpful. I have used this about 20+ times pads are still working well.

I've been using a TENS, EMS, and massage combo tool daily, where it's small in size and light in weight; it's also handy for your handbag and it has quickly become a staple in my pain relief routine. The device lives up to its description—offering targeted stimulation that helps ease muscle tension and chronic aches. With adjustable intensity levels and versatile modes, it’s great for both relaxation and recovery. Simple to operate, reliable, and effective—definitely a smart buy for anyone seeking non-invasive, drug-free relief.

Didn't help with the ease of pain at all. Clarity of instructions difficult to understand mostly worked out by trial and error, don't recommend it
