I bought this off of Amazon for just over the $10 mark, and this stuff is great. I saw a commercial for this on social media talking about how you just spray this stuff in the barrel of the gun and chambers, meaning you don’t have to clean you guns nearly as often. I can definitely say this works as I find myself very rarely having to clean up or due maintenance cleaning on my firearms.
The only con i can think of is it is a bit messy since there is no straw to help control the spray, but it does the job and works well. Hopefully they will redo the sprayer some how to help control the spray direction.
Overall, I highly recommend this to anyone into firearms looking for a solution to constant cleaning.
