Review on Screw Top LD5GRLBK006: Efficient Leak Protection by Leaktite Corporation by Victor Garro

This is a lower quality than the more expensive Gamma caps. They seem to work well and as advertised they are just thinner and not as strong. I haven't decided yet whether to spend the few bucks more on the gamma caps. I have a lot of them at the moment so I don't expect a decision to be made in the near future.
