OK: For mat itself.
The ones we got delivered, we first had to open the valve three days are released so that it unfolds again automatically free.
Why not immediately nachpusten with the mouth?
Because it can happen that the inside parts tear the foam (can also submit at the expensive Th ... est happen!).
Dear patient and let make the mat the first time ...
The mat is exactly as described, quality fits as already mentioned, etc. etc ....
Just as "no longer so very lightweight Männeken" should choose a little more than 3.0.
If I had it previously considered more closely, I would have chosen the 5.0er.
Nevertheless, we do not send back this because they still served their purpose.
More height provides grip more comfortable.
About the valve can be argued ... sure there are better solutions, but we have no problems.
Who has the nachpusten problems should press when the valve is fully open in the direction of this mat, then passes no air and lands in the correct mat.
Since my greed was my problem with the thickness of the mat / is, full 5 stars.
Achso..bezüglich of quality:
Our other 4 mats of Grand Canyon, we now have several years ...
Changing temperatures, from Ars..kalt to 50 degrees at noon in the shade (tent)
Main deck load, maximum load by playing children, fully nachgepustet, normal inflated ...
I think we all use scenarios already ...
Even on bare stony ground we have already used a mat.
The mats are still OK .... well except for one, for this one so the replacement should be.
There, the bond had broken near the valve.
But that was probably my / our debt: Almost 65Grad in the sun fully inflated (nachgepustet evening and forgot to open in the blazing sun of the following day the valve).
Since such a mat may also acknowledge the service ;-)
I hope my / our experience help others to make decisions helpful.
