Amazing. Inflates a boat in 3 minutes. And deflates it in the same time. It also has various nozzles to inflate other things like balls, for example

Very good job in inflating and deflating, due to the double action.
It has been tested for air mattresses.

I still haven't figured out how it works and basically if it works at all. Anyway, I haven't been able to easily inflate anything.

Excellent! I got it as a backup for an Intex electric pump in case things get tough... With the electric pump, I inflate the sleeping pad to 90-95% and then finish it off effortlessly with the pump... A must-have item from me

Okay, it just rocks. I was hesitant to get it along with a large inflatable flamingo... Luckily I bought it... It inflates but also deflates relatively easily. Now inflatables are a breeze to blow up. I recommend it because as a father of 3 children it helped me a lot

A product that is worth 100% of its money. Fast inflation and deflation of air mattresses, even inflatable boats. Incomparably better than many electric pumps for inflatables.

An inflatable 1.60m children's toy that inflates and deflates and some inflatable beach toys with great comfort. It is also lightweight.

It was purchased solely for inflating an air mattress, very good at its job, I had inflated the double mattress in less than 1 minute.

Very mediocre pump. It has a lot of volume, so I wouldn't recommend it for travel, but mainly because a little rubber piece inside constantly comes out of its place, resulting in the loss of air pressure towards the outside. The reason I am writing this is because I am looking to replace it

I never managed to inflate a basketball to the point I wanted because it releases air when pumping. I imagine that when trying to inflate something with less pressure, it will work better. It didn't suit my needs, though

Amazing pump with a very basic deflation function, especially for children's inflatable sea toys that are impossible to deflate otherwise

Very fast in inflating large inflatables such as children's boats. Comes with adapters for different sizes and a needle for balls. Has a suction function for easy deflation of large inflatables. Good construction, seems durable.
The only negative is that when inflating a ball with the needle, it gets tiring during the pulling phase (raising) due to it being double action.
However, I prefer it over the electric one I bought from a German supermarket chain.

It's a great pump. It inflates the whole playground - pool and it works perfectly. You choose the nozzle that suits you and everything is fine.

Perfect for me, I bought it for my little one's inflatable toys. Inflatable pony 1.05m x 0.50m x 0.50m, I inflated it in less than 10 minutes. I think it is ideal for this type of use.

I have never seen a worse pump, I've been trying for 10 minutes to inflate a basketball and the air it puts in when you push down the lever, it takes it back when you lift it up. Tragic

I am very satisfied. I have no point of comparison with any other similar pump, only with a small cylindrical one in accordion style that is dramatically inferior to this one
