Affordable fill kit anyone?

Does anyone have experience with this extremely affordable fill kit?
Sure, there's no gauge on it so that's partly where the savings come but I still think it's tempting.
I already have three fill kits but You know You can never have too many of them.

I have a few scuba tanks and at least one more to come.


And while we're at it, what's with the short hose on all of these? Some industry standard as safety measure? You got to hate that. I'll get me 4 to 5 feet long ones...
 
AGT provide sort of the same with their rifles, well my vulcan 3 at least, it is a very basic thing.
I have not used it or any other similar ( short tether ) since like 2014 or something, i shoot tethered and so need a 1.5 M long tether CUZ bottle are on floor and not bench.

For filling they work just fine, but i can not be bothered filling i connect- shoot and then many hours later i disconnect and stop shooting.

I have like 3-4 surplus of these short whips, one also came with my new fill station i have yet to install on my CF bottle.
The short whip on the new kit, probably the premium one, as a Dane all it need is a little white, a American would need a little blue too.
