This mattress is worth their money. the packaging makes at the seams rather quickly tired and I think it's only a matter of time until the strap breaks .. but that's the least of our problems. the pump is very powerful and blows the mattress in a very short time at a low noise level. overnight loses the mattress easily to air, but that's with renewed, recently connect the battery pump quickly compensated! All in all, there are 4 of 5 stars.
