Sehr gut zum Aufpumpen der Gymnastikbälle...

Todo perfecto. La compré para inflar una pelota de pilates. Para balones con otro tipo de válvula más estrecha probablemente no serviría

I bought this pump for blowing up modelling balloons. Works brilliantly, in my opnion it works better for this purpose than the typical Qualatex type pump you encounter a lot. It's quite compact as well, which makes it easier for me to take with me. For that price, quite a good deal.

This is a nifty little pump that works well.It's very cheap and comes with two different nozzles - so it should fit virtually any exercise-ball on the planet). The makers have also included - in a burst of silent generosity - a rather helpful little gadget for getting the stopper out of your ball AND a spare stopper. Huzzah!I'm reviewing this product solely because of how I have been reduced to a kind of drooping despair for the future of mankind, by the fact that some people are giving this useful gadget one-star reviews because - wait for it - "it sucks air in, as well as blowing it out."It's difficult to know where to start with this as a reason for complaining about... a pump. Pumps pump. They suck and they blow. That's what pumping actually is: suck, blow.Anything - anything on the planet - that blows air out, must also suck air back in again, in order to be able to blow the next lot of air out.Put it this way. If this pump *didn't* suck air in as well as blowing it out, it would implode.If it had a good-enough seal and it kept on blowing out without sucking in again, it could - in theory - create an internal vacuum so powerful that eventually it would suck itself inside out, taking the whole known universe with it - before disappearing with a tiny "pop!". You wouldn't be able to hear the pop (a) because of the vacuum and (b) because you would have already have been sucked into the pump and died.Ok - so maybe it wouldn't actually pop: there would be no atoms left to be allowing any sound to happen - but the whole idea of wanting something that only sucked without blowing reminded me of the relentlessly sucking vacuum-cleaner that used to turn up on 'The Pink Panther' cartoon show in the 1970's and which did go 'pop!' as it disappeared.If you prefer your metaphors a bit more recent - and given how closely he approaches a value of infinite suckiness - imagine a pump that only ever sucks as having a similar effect on the universe as Donald Trump has to the level of intelligence in any room he walks into.But I digress. Getting back to explaining this pump very slowly for the doubters: this pump works in three simple stages.1. You blow a pump-full of air into the ball, as you push down on the plunger.2. When you pull the plunger out again, the pump takes in a fresh lot of air through the four holes in the end of the plunger. Think of this as being a bit like an athlete taking a gasp of air. Or as being the total opposite of what Rudy Giuliani did when he twice managed to express his wrath *from both ends simultaneously* during a Hearing into Non-Existent Voter-Fraud in Michigan. You should google this. It's nearly as funny as Four Seasons Total Landscaping.3. You then blow another pump full of air - which is the fresh air the pump has just sucked in, during stage 2 - into the ball, as you push the plunger down again.If you pump very, very slowly, I suppose it would be possible for the ball to be losing air through the nozzle faster than you are able to pump air in - but you would have to be pumping very, very slowly indeed: more slowly than the speed at which Donald Trump finally reached for the phone to send help to the people sheltering in the Capitol building on the 6th of January - so, say, about as slowly his decision to tell all the people hitting policemen on the head with signs saying 'Trump' that maybe all this violence was a bad thing and it might be time to go home.If you are not fit enough to pump fast enough to stay ahead of the air slowly escaping from your ball, you can either have a little rest by covering the four holes at the back of the pump with your spare hand, or by taking the pump out altogether and blocking the hole in the ball by resting your fingertip on it.Think of pumping quickly and energetically as one of the ways the ball is keeping you fit.I hope this review helps.
