You will need a dual channel unit like this one:-

TEN's does work, I used it for a couple of years before I had a THR.
Getting used to the system and tuning it for your own requirements can be quite a task.
The wires going down to your knees can be a problem, but in the end you would get used to it.
There is quite a lot of useful info on the above Amazon page.
A rechargeable battery is a great help, if you are going to use it regularly.
Tens machines are brilliant I was using one as a guinea pig when the NHS first started using them nearly 40 years ago and I still use them but my advice is go for a multi programme one I get all mine from naturesgatetens.com.
And I have found them very helpful look at the website then phone them for advice on the right machine for you
Hope that helps
