In my more desperate moments of failed hand milking, I'd dreamt of getting my hands on an electric milker. But they are:
a) HUGE - big time overkill for three little goats,
b) Expensive! Three and four figures expensive. Do you know how long I'd have to milk my goats to get $700 worth of milk out of them?
c) Complicated as all get-out. Pulsators, tubes, compressors, yada yada. Too many things to break. And, if you have to have a degree in mechanical engineering to assemble the thing fresh each day, well... it's not for me.
Which is why a Henry Milker was so appealing to me. It has seven parts total - a hand pump, teat cup, two tubes, a quart mason jar, modified jar lid and ring. C'est tout. Now, what they charge you for this simple little set up is a bit hard to swallow at $139, but I used the code "DAIRYGOAT" at checkout and got $10 off and a spare jar, lid, ring, size small teat cup & pair of tubes, which lessened the sting of the price tag a bit.
Setting up and using the milker were both a piece of cake. Even I can't mangle it too badly when there are only seven parts involved.
The quart jar comes with a lid that has had two hollow plastic spike-like fixtures set into it (I can't, for the life of me, think of the proper word for these things). You set the lid on the clean jar, then tighten it down with the ring. You affix one tube to each of the spike/receivers. One of your affixed tubes will now hook up to the hand pump, the other tube, to the teat cup (a large, blunt syringe with the plunger removed), and then you're ready to milk!
As far as using the milker, the advice that I have to offer is:
a)After cleaning the udder/teats, you'll need to clear the teat by hand milking once or twice before attaching the milker. This will not only clear any old/funky milk and debris from the orifice, but also encourage your goat to let down her milk. (I also massage the udder a little while washing her up. If all else fails, you can give her a little bump like the baby kids do to get the milk to let down.)
b) You need to be sure to get your teat cup straight on. A bad approach can lead to pinching, which can lead to a kick in the head.
c) Watch the pressure! The literature that comes with the milker advises that you not go above 10 on the gauge (I don't know what the unit of measurement is. PSI?). I've noticed that my does require between 5-7 to flow well. The lower that you can get away with, the better.
d) Let the pressure fluctuate. Once you have the milk going well, letting the pressure fall (and consequently, the milk flow) will not hurt your overall output. In fact, keeping the pressure constantly high without a break can damage the teat over time. I pump mine up until it begins to flow, maintain that pressure level for 10 seconds or so, then take a break from pumping to let the pressure fall gradually. When it hits a point where the flow is down to drips, I pump it back up.
Besides the relative affordability of this milker versus others, and it's idiot-proof operation, the Henry Milker has one additional benefit - cleanliness. I am a germaphobe, and the idea of milking by hand, allowing hair and straw and God-knows-what-else to fall into the bucket while milking really grossed me out. There's also the issue of the doe either stepping in and spoiling, or knocking over the bucket of milk. These are all non-issues with this milker.
I do still filter my milk, because you never know, but I'm far less concerned about contaminants when using this contained system.
So overall, I would recommend this milker for folks who have just a few goats to milk and are slow or inefficient at hand milking. It comes with a 30-day money back guarantee, which seems like a reasonable length of time for a farmer and goat to determine whether or not this sort of set-up is for them. We're using the heck out of it over here, and the does like it a lot better than my clumsy, endless hand milking, so we'll be keeping ours. ;)
