"Very accurate! Very easy to use!"
I read these reviews and wondered how the Bodybuilding Federation could endorse a product that got these bad reviews.

So, I bought one. I love it!

Now, I can see how some people may not have been able to use it effectively, because it only opens a few inches and is probably more for fit people than for heavy people. Bit if you are fit and just want to see how fit, this is the device for you.

I find the results very repeatable. Each of the three measurement sites have been repeatable within 1mm over dozens of trys.

The Myotape is also cool. Use it and mybodycomp.com to get your body fat percentage and see just how close the number is to the number the calipers give you. Amazingly, for me, the number was identical.

Great product! Much better than my body fat scale which gives me double the number that this gives me.

"Save your money!"
I was absolutely disgusted when I opened the package, and the supposed "Improve your measuring skills" booklet was not included. I also need to mention that the measurements may be close, but the calculation is RIDICULOUSLY inaccurate. I sent a complaint to the company and recieved no response whatsoever. Manual calipers may be less convenient, but at least you can do the math yourself, and come up with an accurate number. Save your money!!

"Very easy to use"
True, the included instructions are a bit hard to understand, but once you get the hang of it, it's pretty easy to use. It might be a little easier for men because the sites to measure are easy to get to (chest, tummy, leg). I found the FatTrack to be pretty consistent and the MyoTape is really easy to use. If you want to get just one..I too would suggest the myotape..you can use www.mybodycomp.com to calculate your body fat. Something I just found out was that this item is reimbursable from most insurance medical saving accounts.

"Forget the Caliper and get the Myo Tape only"
The problem with this caliper lies not in the product itself but in how hard it is to take consistent measurements. I don't doubt the caliper's accuracy, but I've tried measuring myself over and over and the values I get vary by as much as 15 mm. The instruction manual that it brings is far too basic and does not give a clear understanding of how to take measurements. I believe there are manuals for sale that are supposed to help you get consistent values, but I don't own one myself. Without such a manual, I would advise you to spend your money elsewhere. Also, the product description states that you can take measurements yourself, but unless you have four arms, it is impossible to do without someone to help you.
The Myotape, on the other hand, is very easy to use and will give you accurate measurements every time. It is the only reason I rated this product with 2 stars instead of only one. You are better off buying the measuring tape by itself.
