2-stars because I've owned other TENS/EMS devices of better value
on September 27, 2012
First off, this is an excellent portable TENS device that only uses 2 AAA batteries (incl.) and has 2 electrodes, but if you do some more research you'll realize it is a little high-priced for what you get.
I can only give it 2-stars because there are similarly priced TENS and dual EMS devices for the same price that have 4 electrodes that are far better values.
I first got one after being hooked up to a "commercial" one at my chiropracter's office. Later, I went to a different chiro and they had a small portable unit and I was like, wow, it works just as good. Thus, I searched Amazon many years ago and found a TENS/EMS dual unit with 4 electrodes for right at $50 or so.
On top of that, the one I ordered many years ago, uses a longer lasting 9V battery, has a few dozen extra options, has more levels of sensitivity and more power output AND...also has an AC adapter.
So would you pay the same amount for something with 2 less electrodes, has less power, less configurable options, and only uses battery power?
Then, another consideration is..replacement electrodes. The type that I purchased uses the standard electrical-stim electrodes that I can purchase from any vendor. This OMRON unit uses their own connectors, therefore you have to go to OMRON to purchase them. I haven't priced them out for this OMRON unit, but I know a dozen vendors sell universal electrodes for my old unit.
On my old unit, I can set sensitivity for each pair of electrodes, so let's say your whole back was in pain, but the lower hurt more. You can put 2 electrodes on the upper/middle and 2 electrodes on the lower. Then, you can turn up the power on just the lower as needed. Also, I can use just 2 electrodes if I wanted (like the OMRON).
Here's some helpful criteria to consider if you are looking for a device like this:
0. My disclaimer - I'm an engineer, I work in IT, I am not a doctor! ALWAYS ask your doctor before use and never use this near your neck or the front of your chest (or chest to back), please follow all directions in the instruction manual; use only as directed!
2. How many electrodes? (Should be 4, IMHO)
3. What is the electrode connector like? Can I buy more from any place or is it a proprietary connector that I must buy from the same manufacturer (like this OMRON)
4. Does it do TENS and EMS or just TENS ?
5. Can I use AC power to save on battery when I'm laying in bed?
6. Is it portable? Does it have a battery power option?
7. How configurable is it? How many options? How customizable are the various programs?
8. Ask your Chiro which one they use if they have a small portable one
Once you consider the 8 criteria above, you will understand why I give this one 2-stars.
