Milton S-3203: High-performance 360° Swivel Grease Gun Coupler Review

Based on my observations, this swivel coupler is poorly designed and does not work as advertised. The swivel mechanism constantly jams, making it difficult to use. Though it appears to be durable, it's simply not worth the hassle.

This is meant to be a hard-to-reach general-purpose grease nipple, but it's too big and bulky for that. Space isn't equal

So far everything works fine, holds up well on the transom, spins normally, no leaks. You have to pull the collar down to rotate it, then it locks into place. I don't know why, but I thought it was made in the USA, it's not. Made in India, at least better than made in China.
