I bought about a dozen of the Giant guns, per recommendations here on the forum. They were by far the worst piece of excrement I've ever seen. About half of them were stuck "wide open" when brand new. I had to wait a couple of months for them to be replaced, so in the meantime I had to buy some more. As was said earlier, the plastic broke easily. Within a year, every one I bought had failed and was tossed in the dumpster. I've been using Suttners ever since.
