I've been using this bed as my main bed for almost three weeks now. While I don't want to make it my permanent bed, it'd much better than I expected.
Pros:
1. Reasonably firm (you can sit on the corner, for example)
2. Deflates very slowly, so I don't top it up every day
3. Quite comfortable for an inflatable bed
4. Very high, so you don't feel like you're sleeping on the floor like with many other inflatable beds
5. Delivery was very quick
Cons:
1. The sheet cannot be tucked under the mattress (obviously), so in the morning it's in a total mess
2. It squeaks. A lot.
3. You will want to put an extra duvet under the sheet, otherwise it'll be cold in the morning (like with all airbeds, I guess)
4. It's a bit short. I'm 177cm and it's just enough for me, may be unsuitable for tall people.
5. It comes from Germany with a European plug, so you'll need a EU2UK converter, which is not supplied.
Overall, I'm very happy with it and I would recommend to buy it, especially given a very reasonable price.
