Neat DIY CO2 Gadget

[Super_Blueberry]

I was browsing eBay today and I came across this neat gizmo. I personally went through a number of homemade caps solving pressure issues after reusing them time and time again....and thats just in the few months I did DIY before my upgrade to pressurized. Maybe this has been available forever and I just never saw it, but I thought it was cool. Wish I had it then.

I saw these also. Since I still use DIY on two of my small tanks, think it would be a good gadget to have.
