I respect all the 5-star reviews of this product, but I have a different opinion about it.
I give it a three star rating for the following reasons:
The plastic is very, very flimsy. The tape feels like it won't last too much because the material is too soft.
The main reason why I removed stars though, is because this tape has nothing accurate about it.
First, there is a button in the centre that should allow the tape to be freely pulled out, or to unlock the tape so that it can go tight around the body part you're measuring. This button is pointless. You can just pull the tape out just fine without pressing it, and when you press the button to tighten the tape, you find that when you remove it from your body, it still goes back a centimetre or so inside, so it has nothing accurate about it.
Second, for this price they should have sent instructions on how to measure some body parts, but there was no such thing in the packaging. For a product that tries to be user friendly, I find it quite ridiculous that they didn't include instructions on how to properly measure at least your waist. Some people might read this and think that it's a silly thing to say, but when you never measured yourself before, you really don't know where to position the tape. A Google search didn't help.
If you're just writing the data on a piece of paper or typing into a spreadsheet, it could be okay, but when you're using it to record data into a tracking website or software, or because the doctor asked you to, then the lack of guidance becomes an annoyance and the lack of accuracy is shameful.
For a glorified piece of plastic that costs almost £6, this product lacks accuracy, quality, and instructions. The packaging is also bad. I'd not recommend this item. You would be better off buying a normal tape to measure yourself, this doesn't make it any more easy than that and it's one more thing to fiddle with. You can also use the tape to measure other stuff, whereas with this, you'll only be able to measure your body.
Bottom line? The product is not worth the price, so save yourself some cash and buy a normal tape.
