IF 4000 Dual Channel Interferential Unit

This unit delivers the same effect as the big one in my PT office. IF seems to help me more than TENS. I'm really happy with it. I use it on upper shoulders/back so I need help placing the electrodes. It's a simple unit and easy to use. Don't plan to use it on batteries - it draws too mich power. Use the AC adapter for best performance.

Great unit,not as intense as others but just right for my pain levels.

I purchased this IF4000 and love it. Sadly I dropped it and then purchased a second unit. Intermittent use throughout the day has finally reduced my pain significantly. I still deal with extensive swelling.

This unit is very effective. My wife has had recurring hip pain and even our TENs unit was not providing lasting relief. She went to the chiropractor where he used an interferential stim unit. This provided an effective, lasting therapy to the sore hip area. We elected to search to see if there were affordable units available. TENSpro had the best price on home grade units, hands down. It was delivered sooner than originally expected in perfect condition. She has used it several times and told me that it works well and provides lasting relief.

This thing works great and helps get my muscles relaxed during the times I am away from the chiropractor.

This unit works great for my wife and I to relieve arthritis joint pain. 15 minutes two or three times a week is almost as effective as acupuncture with electrode but not as expensive.
