Just my opinion that I should have a pressure gauge so that people can control the volume of air and that they don't have an accident with the mattress that can splutter.

The product is shipped quickly and the packaging is very tight upon receipt. I went camping and tried it out, and the inflation effect is very good. The automatic electric pump inflates quickly and conveniently!

This mattress is indeed good and of high quality. Whether it's at home or outside, it's very convenient to use and worth purchasing!

I have 3 different mattresses for outdoor activities, and this one is of the best quality. I am very satisfied with it and I recommend it
