I have been reviewing the blog and the forum because I am very interested in getting a machine. It seems that the "handle" on many of these machines is the same one, and seems to be the weak link, with many experiencing failure. Although Dick makes sense that x mj at y hz will do the same thing, whether it comes from an expensive or cheap machine, I am leaning to a little more expensive machine with a different handle system, just to avoid repair headaches.

Many of the links that people post to machine sites go stale, so you cannot look at their machine. However, I wonder if I have found the model that James in Irving Texas got. It has an applicator shaped like a gun, 2 million shot life, and it is a compressor based system (pneumatic) and the picture shows an "air filter" on the rear. I do wonder if the "gun" shape is harder or easier to use in self application. At the moment this device is shown at ***3w.aliexpress  .com/item/4000010110183.html?spm=a2g0o.detail.1000023.3.14fa7ad73eBOcW***  (had to break up link address to get it past system, and I tried to paste a picture, but system said I had not posted enough posts to include a link.) and several other Aliexpress addresses. It is called the "Magic SW19" or "xxxx SW19" on other offerings (plug in a brand for the x's). It goes to 8 bar and 1-21 Hz, and has 11 heads. It says shipping is 11-25 days, but free. 
Does anyone have experience with such a machine? Or using a "gun" type of applicator in a DIY situation?

With yours 8 bars max i was just wondering/worrying for a second cause right now i use 9 bars at my machine, so 8 would be too few for that

Dream, I thought I remembered Dick saying that he used 2 bar.

So, I received the Magic SW-19 machine. Characteristically, from what I have seen here, it came with no instructions and had an initial screen requiring a code. It also had a minor crack in the top left rear part of the case.

I went to my account on Aliexpress and the order(s) list and found chat box. Even as I typed, I started to get a response from “Evelyn”. She immediately sent me links to videos (which I have not had time to look at as it arrived at a time such that I did not get to open it until 11:00 pm) and emailed pdf’s. I am to send pictures of the crack.

Now a question about application. The machine has an ED setting with a “C” (comfort?) option and a “P” (Professional?) option. The latter gives more impact quantity options and different frequency and Bar options. I tried the default 8 hz and 2 Bar. I used ultrasound gel. In addition to the impacts, I also felt stinging, like an electro-stim/tens unit with poor contact. Pressing harder did not change this. 

Has anyone else experienced this stinging? Any suggestions to eliminate it? Changing Hz affects it somewhat but does not eliminate it.
