Before I purchase one of these who uses what and what's best... Google says the topeak blaster is best, the lezyne looks good also. Are they as good as they make out??

Iv got the airshot but I don't rate it

How much are they? You can buy a small (25l) compressor for not much.

My small compressor won't do tubeless as you cannot dump the air fast enough ( might by the poor quality inflator I bought mind)
A.fire extinguisher is a far cheaper option ( and larger volume)!and I doubt the pumps have any more air volume than the airshot but no personal experience.

I have the Topeak Joe Blow Booster. I needed a better track pump anyway so bought that rather than an airshot

Works great. Only annoying thing is if you need to do it a few times because it's a crap tyre seal or similar, you tyre ( ) yourself out a bit pumping so much. But overall it's good

Better than a compressor for me because it can be taken with you or moved around more easily, plus at the time I didn't have space for one

I bought a Lifeline Airblaster. It was on offer.

I've only ever needed it for the Fatbike tyres, for which it worked just fine.

I've got the Bontrager one, no complaints from me. Ideally I'd have a compressor but until I clear the garage that ain't happening. It's also handy for taking down the park to launch bottle rockets.

Ta all, stu I can use the compressor at work which inflates to 150 psi works a treat but I need something for home and I could probably do with a new track pump my old Joe blow must be like 20 yrs old now

I also have the Topeak. Silly money but does exactly what it's supposed to.

TBH I never had that much trouble with a normal track pump (Topeak or Spesh).

Lezyne here - it's been excellent.

I have the Lezyne pump and also a compact 2hp Super Squirrel compressor and to be honest, the pump never gets used now.

The pump is OK for most MTB, but for road it isn't always perfect and here a compressor just works much, much better having a constant airflow.
Whatever you get, make sure you get plenty of spare valve cores as it is often a clogged valve core that is the problem. On some you can connect and release the air with the core removed and that can be handy for faster airflow.
