Things I liked: It does the job, and will last a lifetime. Adding just two drops 4 times per year to the chamber of your springer will be all that is ever required.
Things I would have changed: My bottle came with the AEG label on it. I prefer to recieved the pictured product. I suspect it all the same material.
What others should know: Despite supposedly being a silicone oil, this product will detonate slightly in higher-powered springers. Caution is required to never "over- oil". However, I was never able to use so much that I caused any damage, and the detonations clear our after 3 or 4 shots.
