Doesn’t sound too bad then for 15 quidI have two of those nippleshop ones, they work fine but the older of the two burst it's piston seal...which is a really crappy design so I ended up turning a new piston with an o-ring groove instead.
They are worth £15, and it's worth having two so you don't have to swap the ends over....and invariably the loose one goes missing.
I bought one of these 7 months ago, seems well made.
Though price has gone up £4 since I bought it: https://www.pressparts.co.uk/pump-gun-with-2-nozzles-for-grease-or-oil-c2x14443942
there crap the myford onesI bought the Myford one from Myford when the had an open day sale, they were still in Beeston then. Spendy but works.
Not sure if RDG sell them now...
