[Body Fat Caliper and Body Measuring Tape] / Skinfold Caliper and Body Tape Measure - Includes Free Software, Video Interpretation, and English Manual - BOZEERA© - The Complete Set.

They measure body fat relatively accurately. The material used is not cheap and feels fine, and value for money is there. It's incredibly fast to measure, and very functional.

For the price, I think this product does a great job, hence the 4* rating. I think it's fine to track progress and get a reasonable idea of where you are (rough ball park, though).The tape measure is great, no fault there. The calliper itself is a bit flimsy and fiddly to take measurements with, if you're doing it on your own. If you have someone helping out with reading the measurement it's much easier, but that's not always the case.

Very nice and handy tool. It was very easy to use since it has a pressure meter so you know you’re pressing hard enough.Came with a QR code to their online calculator and a video that shows you how to use it.The only negative thing I can say is that the millimetres are incremented 2mm so it’s harder to know if you hit 5mm or 6mm etc

The tape measure part lost its end causing it to be unusable after a few months .shame as it worked ok before this. Seems a bit fragile for regular use .

No instructions so a bit useless really

I've found this completely unusable and inaccurate. Firstly each line seems to represent 2mm's instead of the one. As you can see in the image there are five lines instead of ten between numbers, so each denominator must be 2mm. This is an issue because it's written so small that if like me you are reasonably lean and usually come up in between you have to guestimate what the reading is. As a 2mm variance makes a huge difference when you are a lower body fat percentage. From other calipers I have used I can usually measure half way between lines, so say 11.5mm on an abdominal fold, with these it is such a tiny movement between 10mm and 12mm it's impossible to read accurately. As the writing is so small it essentially makes it difficult to take measurements yourself (using the Jackson-Pollock technique). I have also put a second image so you can see the size difference between a normal pair and these. Don't waste your money, I really don't understand how these had such good reviews. Perhaps it's people not used to using calipers etc.The tape measure seems okay but that wasn't why I made this purchase. I won't be sending it back as I'd like to keep the tape measure and it was only cheap anyway.

Good quality calipers for the price. Tape mechanism tends to jam but is okay. No official app but there's Body Fat Calculator (PRO) at https://bodyfatcalculator.pro which I find great. It's a one-off £10 for all formulas which is a relief in the world of silly subscriptions.

Excellent product, perfect!
