From time to time, you get bit in the digital world. Thank goodness I'm somewhat handy mechanically (sorry about the pun). The case reminds me of something you would carry 45s around in (records, not guns). The pressboard was a disappointing construction material, but the metal ends cap, the metal surround, and even the metal hand strap ends were a nice touch, indeed. Slap the name Marshall on it add a couple of knobs that go to eleven; wham, everyone will think you have a Marshall practice amp. Inside I found shotty workmanship with some quality components. Motor, Diapham, Air Handler, and even the basic framework looked pretty good. It just needs a little love. If you are mechanically inclined, then this isn't a big deal. We modify everything around this house. The carrying box to me isn't the problem. The milkers are the real problem. 2" plastic tube with silicone base sleeve, two 2" o-rings, a 1/4" threaded pipe extension that you would find in a cheap Torchiere lamp, and lastly, a rubber cap with a one-way air valve. Like everything else in this world, you can buy the assembly, but you can't buy a replacement leave. Oh, one-way air valves in The Milker Cylinder, that rubbish, vinyl, whatever cap is a joke as well. Everything I've listed, you can find at any real hardware or craft shop. Wait for it The 2" silicone-ish type sleeve isn't replaceable. I would think one could buy a 100-foot roll, and as it breaks, you cut off a new piece, and away you go. Wrong. Months of looking, I couldn't find a thing until I found a replacement, rubber milking sleave for dairy cows. DOH! Problem solved. I bought a couple of the cylinder assemblies, too, right here on the AMAZON. Everything ready, the wife and I are going to have a little over the weekend... Well, I was wrong again! I plugged this thing into a wall socket, and it started to dance across the floor, completely out of control. Now, if you have never seen a dancing box that resembled a 45 record carrying case or, in my mind, a mini-stack, it is something to see. So much so, my wife spilled her ice tea. Anyone can tell you, in the south, that it is not a good thing to spill your sweet tea. What you are looking at is the USB speed control, circuit board. The picture says it all, and it's just the way I found it, once the case let go and it opened. Houston, we have a problem. Knowing there isn't any way I'm going to be able to buy one. I'll build it. For giggles and a small light show, out in the box marked pieces, parts, and things, I had three antminer, rotary fan controllers. Don't ask why I had them; know they came out of my first water-cooled computer. Three of them together sounded like a 727 taking off at full power. If you enjoy like I do, tearing something apart to make it better, then buy one. If you do not have the patents, buy something else. The genuinely sad part of this story is that everything about it is true... Revise: I just bought what I needed for less than twenty dollars. How about that!
