Hi,
I know a couple of my clients have the home use version of my professional machine after they had treatments with me. Luckily the company I purchased my machine from, pay me ยฃ100 for each client I recommend to them, so I have made myself a tidy little profit so far.
The feedback they have given me has been good, the machines cost them around ยฃ400 and the arrays last around 100 uses and are ยฃ35 to replace, I also have clients who pay monthly for their machines and they only pay around ยฃ20 a month.
The machines that they use for home use also have a lot of the features of a professional quality machine, such as LCD display (which tells you exactly what the machine is doing, instead of having to guess how much time you have left and how much salt to add to the water) I know a lot of the cheaper machines don't have this and it does save a lot of time.
I would recommend home use machines for my clients, but remember you do get what you pay for, I've tried these cheaper machines and in my opinion they really aren't up to the job
