I posted this sort of review on another thread recently. Pasting it here.
I have a Henry Milker and I don't love it but I don't hate it either. I used it last year because I have carpal tunnel and just could not milk all by hand. But each of my girls have peculiarities with their udders (I think they were all someone else's culls for these reasons) and I have to start and finish the milking by hand and one of them is much faster by hand. With the Milker, there's just a very fine stream of milk so she takes FOREVER but by hand it seams normal and much faster. One has very saggy and bulbous teats and will not tolerate the machine at all but is perfectly fine with hand milking. I wonder if her teats are like that because of a continuous pressure Milker before I bought her.
So I just started milking for this year and used the Milker partially today. I will be looking for a surge Milker very soon. I guess here is my "review" of the Henry Milker:
I paid extra for the double Milker that came with two jars, two lids and the attachment to put them together so you can milk both teats at once, but I did not pay the extra to get a warranty. The very first time I put it on the very first goat, she gave it one small kick and turned my double Milker into a single. One of the lids broke with no way to repair it. I have not bothered to purchase another one. The gaskets that seal the lid to the jar allowing the suction won't stay in the lid reliably and if you have to change jars during milking you have to really watch that the gasket doesn't become misaligned or fall into the milk, making it hard to find. But I now have an extra gasket since the second lid is broken. The pump is not very heavy duty so you have to be careful with it. The crystal on the front of the gauge of mine keeps falling off, but it still works. The tubes are a PITA to remove from the other pieces, which is probably a good thing because you need a tight fit. But I actually can't get them apart anymore so I wash then all together. Probably not the most sanitary way to go but for now I'm only milking for soap or baby goats or calves so we are ok. The pump gauge goes way past 10 but the instructions very clearly said not to go higher than 10. You really need to watch the pressure. I did not know that the constant pressure was bad for the goats until after I started using it. I probably would not have bought it if I had known. All in all, I don't think it is a bad thing if it is temporary, but it is kind of cheaply made but a little pricey for the lack of sturdiness. You could probably build your own much cheaper and since it is not healthy for long term use, why spend a bunch? It did help my hands a little.
