Very good tens machine good amount of various settings and works

Battery lasts for ages, portable, customisable programs that help you reduce tension and soreness. This can be used as a warm up or muscle recovery tool. I don’t tend to use the TENS muscle option but I regularly use the massage options. I like that you’re able to set different programs and intensities to run simultaneously between pairs of electrodes, super handy if used on different body parts.

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.

Compact in size, light and not bulky. The machine is easy to use but read the instructions so you know what each button does. I have several machines and this one is easy to work and holds it's charge very well.

This is a great unit with very good power output and a great battery life. However, I have now had 3 of these units of which none of them work properly. All 3 units had power going to 2 pads rather than the 4 the unit supports. Really disappointed as it's a great little product. The images below show the 3 model numbers of the units. Two are the same number and one is a different model number. In all cases only 1 pad each side received power.

Very complicated couldn’t not read instructions
