I purchased a G5 massage tool for my massage practice. I used it 2 times before it started malfunctioning. I contacted DHgate who put me in touch with he seller, who gave me a work around where I had to open the product and adjust the circuit board. That worked for a short time and then messed up again. I did this 3 or 4 times. Then I contacted the seller back and they sent me a new circuit board, on which the connectors didn't match. Their communication through all of this was very slow. Now they won't even respond. I have contacted DHgate many times through out this process and all they tell me is that my order is closed so its out of their hands, but they will contact the seller. Which has done nothing. It was a waste of money and a huge pain. I will never use DHgate again and will tell all of my fellow massage therapists and students the same. This has been an unprofessional experience. There is a lack of integrity and this feels like a huge scam.
