its a nice handy sleek pump and all but its awful for long term. the top rubber piece is going to tear soon for mine. ive only had it for 1 month. it gets harder to pump when contaminated but you can service it by unscrewing off the top piece. now you have the lower section and the hallow section. get a napkin and shove it in as far but you must have a good grip onto the napkin or esle it gets stuck. if it gets stuck try a pencil or its it stuck stuck get some superglue and find a stick like a pencil and shove it in and wait a few seconds with some force. you can screw and unscrew it to test if it feels better. would recommend? no

No issues so far. Pump is easy to use & inflates a tyre quite quickly.

Pump works great, good size

Solid pump with double the internal volume of what I had before. Requires a strong hand to hold it but at least it will get you close to a riding pressure. My previous pump just gave me enough to limp home.
