The first time in my life I was able to wear halterneck bikinis for the whole day. I wasn’t sure such a small piece of plastic would make a difference but it really did. It can be a bit fiddly to thread through the straps if it’s a convertible bikini as the hooks get stuck, but it’s so worth the effort. Not sure why some people say it slides down - stayed firmly in place for me and it couldn’t move because of the knot on top (per the photos on the website). The clear one works with pretty much anything and the black is great with dark colours. Yes it’s visible at the back of your neck, but frankly who cares?

No neck pain for bigger bust ladies, get one now

I was getting a sore neck and remembered I had two of these several years ago. Absolute must with the around swimming top. So comfortable.

An innovative little accessory that I shall be using anytime I'm wearing my halterneck swimsuit. Great idea.

Was really this product would make halter necks more comfortable but sadly it didn't. I expected the plastic to be soft and pliable, but it was actually really quite hard and inflexible, didn't mould or shape to my neck and was actually more uncomfortable than just wearing the halter neck strap. Quite disappointing, as at £10, it wasn't cheap.

It doesn't stay in place as it slides down, but when it does stay in place it feels comfortable. Not worth £10 though.

absolute magic. no more straps ripping my neck apart! YAY!!

Recently tried and tested on holiday it’s a game changer if want to feel comfortable all day long. Easy to use, discreet, stays in place and provides a solution for pressure soreness to back of the neck from halter tie neck bikini tops . Worth every penny. Go! :)
