I HAVE AN F10. WISH I'D BOUGHT 2 . Been debating whether to buy an Alteros booster or go big and get an ALKIN W31 and consider filling tanks and guns for a fee. China saw a market and like most everything my boss bought cheap stuff from china like the 3/8" nuts and bolts. Boss had to buy several 3/8" taps which we chucked up in battery drills and re threaded the nuts. So far I have not heard about long life, & cheap compressors in the same sentences. I keep saying buy quality goods from quality dealers. The header at the top of the forum has a list of them. I know they cost more. I got where I'm by working every hour offered and buy purchasing used trucks. All the same year and brand and salvaged parts, tires, and all the rest and using them till I finally ran our of cheap us made trucks and parts. still have 2 rear windows. 1st real air gun was mdl 27 Diana 40 years ago and worked my way up slowly till I ordered an FX Maverick last Dec 10 2020 ( 40 years) and luckily received it just before the pandemic shut down. Always bought from reputable quality dealers. 3 Dianas, 1 air force arms. an FX bearcat, an FX Impact early model, and a Maverick. This can be an expensive and sometimes frustrating hobby. If more shoeboxes had been purchased less money would have been lost on return shipping and just plain lost. Well enough of my 2 cents I will aspire to keep my opinions to myself henceforth.
