I was slightly skeptical about how useful this pump could be but my skepticism has been misplaced, it really is a device from the future!
I had high hopes for this little pump and so far it's met them all.
1) inflating the paddling pool. Should be bread and butter, and it was, but it did so in very short order. Impressed
2) using it with flextail bags to compress sleeping bags to make more space in our roof box. I was astonished that it removed substantial volume from our double sleeping bag and made it easy to shape it into a cuboid shape making it take up relatively less space in our roof box.
3) inflating and deflating an Outwell Dreamcatcher sleeping mat with valves which are not designed for pumps. This was an outlier because the valves are not designed for use with a pump. But no problem for the impressive Flextail pump - the rubber attachment fitted perfectly and inflated and deflated the mattress in quick time. Deflating with this pump is also saving us maybe 25% volume on previous efforts just rolling to deflate it.
I'm super impressed with this little device and heartily recommend to others. The light is a complete bonus, I'd buy this for pumping ability alone. I also recommend getting the accompanying case for storage of all the nozzles and adaptors alongside the pump.
