I've just had a mucky struggle trying to grease my nipples! Tried last week with my old grease gun and gave up as all the grease did was come out around the nipple heads and so bought a decent grease gun with flexible pipe and a better 4 jaw hydraulic coupling.
Still a bastard trying to get the coupling to sit squarely on the nipples as they seem to point in all different directions and really no idea how much grease to put in.
The remote solution is looking better and better!!
