New Hobby Ultrasonic Record Cleaning

I just followed the link and bought one of these on Amazon it will be interesting to see my experience compared to the others on here.

So based on the OP and others I purchased one of these Happybuy machines. Mine came about three days after the order via Amazon. I got it out of the box today and with a slight bit of trial and error since the directions are a little sparse I got it all together. Not being a chemist and being impatient with all the various DIY formulas that are out there I just bought some Degritter record cleaning fluid (made specifically for an ultrasonic cleaner) from Music Direct. I figured out you use about 5ml of the fluid concentrate per gallon of distilled water. I ran a half a dozen LPs through the cycle (5 minutes) and wiped them with a microfiber cloth that I had also purchased from Amazon.  My initial test was with the water in about 25°C. I do plan to run subsequent tests with a little more heat but I was anxious to give the machine a try and so did not give long enough to warm up the water.
Once they were nice and dry I gave them a play and they were considerably quieter than they had been before. I purposefully used some LPs I had bought at a garage sale in the fall and had never played or cleaned. I did a before and after on each of them and it was very very noticeable.
The machine is easy to use and I have gotten good results in my modest test so far. Now, could I have gotten just as good of results with a good scrub at the sink or using my Discwasher system more heavily? Unknown at this time. I certainly don’t feel like this was money wasted, especially considering the namebrand alternatives run 10 times this cost or more.
