I purchased this product as my gf wanted me to try it for fun. unfortunately, it did not work for me. I'm a local sg dude but my girth is 14.2 cm when soft and 17.3 cm when hard. It still fit my u but after few minutes it starting to hurt; can't wear this product comfortably. Tried forcing it on for a few mins but my balls started to turn reddish almost purple that it hurts. The material feels durable and well-made, but the sizing seems to cater to much smaller dimensions. This might be a great product for those with more modest measurements, but it was unsuitable for me. Consider checking the dimensions carefully before purchasing if you have a larger girth and larger balls.
