I helped my girlfriend use these on her back, I've never used a device like this but found it easy to use with limited instructions needed. It was very effective and achieved results and left the marks after only a couple seconds. She mentioned she liked the results and that she got some muscle and pain relief. The cups are very well made and seem very durable, they didn't cut any corners in the quality here at all. If you're looking for a cupping product like this I'd consider these a great option.
I highly recommend it! It's the most comfortable neck support I've ever had. It folds up easily to fit in the carrying pouch. Great value for the money.
Honestly, I didn't expect much in terms of comfort for a 17-hour flight, but this completely exceeded my expectations. I was genuinely surprised by its comfort level and can confidently say it's a must-have for long journeys. Definitely a recommendation from me!
