Okay, let me start by saying that some propane adapters come with a small can of silicone spray and some don't, this one does not. On the other hand the adapter itself is very well made, full aluminum and some stainless steel innards from the look of it, and it fills very well. I almost didn't buy it because of the review on the silver version of this adapter, but let me tell you, it works just fine.
Very sturdy, the needle will NOT bend or break easily and it fits on the most common types of propane tank without any trouble.
However, I will say that I don't like the way the silicone reservoir is engineered, but it is still better than any alternative that I can see. (way better than without the reservoir at least) And the the link between the top piece (needle) and the bottom piece could potentially be severed and the needle lost. I know I wont have this problem but if you a little unorganized I can see how this can become a problem really quick.
Overall I think this is a great product and well worth the money compared to the price of green gas.
large silicone reservoir
nice selection of color
fits almost any tank
easy to use
chance for the needle piece to become lost (same as any other adapter)
