This company is one of the most professional companies we have worked with in China. Outstanding service from design to delivery. Product quality is top notch.!  I should add Alice is amazing. She is very helpful to ensure everything we required was done. Very professional and did not stop day or night until all requests were sorted.. I highly recommend and will do business with this company again for sure. 

I don't think this device works very well. The flow rate is very poor and I doing feel the effects I have felt with other devices.
