The price seems right for these, but what are the downsides?

If you take it to a welding shop for a refill, how long do you typically have to wait for them to fill it and how much do they typically charge you?

Usually a couple days & they need a test every five years I believe another 25 or 35 dollars.

A coworker's son got me one for $20 a few years ago. The good thing is that they are much lighter than steel tanks. The only downside is that you turn the tank upside down to fill. I don't think it takes but about 5 or 10 minutes to fill. I refill at a fire extinguisher place.

I've been using a 20# tanks for bulk filling for almost
a year now. It doesn't take long to refill it and it's cheaper
than having to fill a 9 oz. bottle at a paintball shop everytime.

S.W.A.G. it!

Next time it's empty, remove the valve from the tank and intall a siphon tube from the bottom of the valve to the bottom of the tank. The bottom of the valve has a theaded hole to attach to.

as long as you know the trick to do it right:

I paid $92 for a full tank a few year back. When empty, trade it in for a full one, it used to cost $16. You never have to pay for a hydro test if you go this route, and never have to wait to have it filled.

If your main tank does not have a siphon tube and you don't turn it over all you will get is gas. The big tank either has to have a siphon tube inside or turned over to get liquid C02 into your gun or small bottle.

well, I have 5 paintball cylinders (9oz), and I can fill them exactly 9oz using the same technique from the same 17lb cylinder (though Iam not sandwiching the paintball cylinder with ice but rather toss it on the freezer for 30mins before filling). So did I get 9oz of gas instead of 9oz of liquid?

IMO there's not any difference gas or liquid. It depends on the room temperature where it kept (read it somewhere). If the temp above 76°F (IIRC) it will form 100% gas. and if it below 76F, it will from part liquid and gas. (edit): 100% fill.

And also (IMO), filling any cylinder from siphon tank is absolutely not required. let's say: the co2 liquid flow from the main tank via the siphon tube, but as soon as the liquid moved to the other cylinder (empty usually - and no matter how cold it is) the liquid will transform to gas. it happens because the cylinder (to fill) itself keep the pressure of the gas, if there is no pressure loss means also there is no heat loss (lot of I mean, heat/pressure loss performed but in small number). if only (lot of) heat loss happens; we may fill the cylinder with liquid or even solid co2 (dry ice).

from this thinking above I concluded that siphon tank only useful for making dry ice (google it about making dry ice from bulk tank).

note:
the main purpose of freezing the cylinder before filling is to keep the pressure of the cylinder lower than the main tank (that 17 or 20lbs). by doing this co2 gas (or whatever it is) still have the oportunity to flow from the bulk to the cylinder.

but that's all my opinions. expert opinion still needed. thx.
