"Bearing and Linkage" - Synthetic Rotor Valve Oil

I ordered a 37ml bottle of linkage oil and got a 30ml bottle of oil without the independent rubber stopper that was mentioned in their YouTube video. I wasn't hoping for the child safety cap it came with either. I can live with the physical differences, but the unexpected changes made me wonder if the price was respectively changed with the quantity of oil included. I contacted the company with the concern and I got a very quick resolve. I'm going to put in another order very soon. The oil seems fine. Good quality. I have yet to test it thoroughly, but I use blue juice and if this compares to the blue, then I'm sticking with it.

This oil has been fantastic! When used with the light rotor oil, my french horn valves have been performing great. I was hesitant at first to purchase thinking this was a gimmicky oil, but it isn't. I have not been disappointed and have purchased again. I plan to continue purchasing this product in the future as I feel it is truly a superior product.
