It probably depends somewhat on your use case. For single guests, you have to run the pump for 30 seconds after every second night. For two people after every night.
So for long-term use certainly a bit tedious... but if you only expect relatively rare guests who don't stay very long, then I would recommend the thing - especially with the current promotion (54.-).

What is the problem if you have to refill the air for a few seconds every second day?
I sleep permanently on such a mattress simply with a topper on top.
