920 Telescopic Hand Pump with Pressure Gauge

Bought 2 of these, one each for my partner and myself for our new bikes but neither of them will pump a tyre above about 40psi despite claiming to go up to 115psi on the packaging. Very disappointing and ultimately useless to us for our needs.

Pump well designed idea of the Brompton.

After lots of tinkering trying to get this to work I’m finding it very difficult, it doesn’t open the valve to let any air in or out. If there’s a video or some kind of instruction manual that consists of more than the images provided, any kind of tips or secret method people are using to get this thing to work send them my way. I can see it being very handy and want it to work quite badly

I bought it because it’s neat, compact, seemingly of good quality, and capable to meet the psi requirement of my tyres on my Triban RC500. It’s only yesterday, while doing the usual maintenance checks on my bike I realised that there is a missing adaptor. Not sure what’s the policy for return or exchange, or if one can obtain an adaptor from somewhere. The pump is pretty much useless. Just a reminder that one should completely inspect a product before purchase and not rely on the presumption that stores would ensure that what they sell are in usable condition. If adaptors are frequently stolen, maybe how the product is sold should be revised.

Once ya get to know this pump and can feel its leaning under higher pressures, it becomes a very reliable tool when ya need it to be. prefer to a normal size hand pump, with the gauge ya can b confident ya aint over-doing it. The handle is what really makes it for me, being able to turn it 90 degrees to the barrel gives ya so much more purchase,and doesnt fell like yav been doing a heavy chest workout down the gym if am going over 80psi - though may b thats not so bad during these restrictive times lol. yes i do recommend it but will say... dont yank the chain like theres no tomorrow! had mine for 18 monthes and still in really good nic.

After a couple of uses this pump literally fell apart , the internal unit fell out and cannot be reassembled. I would not recomend
