Four Channels Are Handy, Modes Don't Make Sense
I like the fact that you can use four channels at a time, even more with the double lead they include. Device is mostly easy to use, except even after reading the minimal (and tiny) instruction booklet I still can't figure out how to sync all channels, so it's kind of annoying when you have electrodes on complementary body parts doing different things.<br /><br />The 30 levels are fine for EMS but the TENS I wish I could go a bit higher. For the money though it does just fine. And the 24 modes are split up 12 modes each for TENS and EMS. A way to customize modes/any customization options besides intensity/duration would be nice but isn't a deal breaker.<br /><br />Time can only be increased in increments of 10 minutes but you can turn it off whenever so it's not a big deal.<br /><br />The instruction booklet (which as mentioned before) is very short and, seriously, incredibly tiny, so the pictures showing where to place electrodes are as good as useless. However this isn't a big deal since Google exists. Still would be nice to have a handy reference you could actually use.<br /><br />The only things keeping this a 4 star review instead of 5 is the modes are very confusing. The modes are chosen based on choosing a picture of either a massage (TENS) or activity/sport (EMS) but the pictures don't make a lot of sense in regards to what they device is actually doing. There's not really a rhyme or reason to it that I can find. It makes it really hard to decide what mode to actually use. That along with the impossibility of getting channels to actually sync dropped it down a star.<br /><br />Cost/benefit of the device though is still very much worth it, especially with the 4 channels, 30 intensity levels, 12 TENS + 12 EMS modes, and quality build of the device. You can definitely feel it working and it seems to be helping, at least short term. I suggest giving it a shot.
