Fast shipment, works great!!
I bought the USB to RS-485 converter to setup a Watlow temperature controller. Good price, It was easy to setup and worked the first time with no fussing. I would highly recommend the product. Having the manual on the CD in chinese is just a bonus. John[...]

DON'T WASTE YOUR TIME
Don't waste your time with this piece of junk. We ordered one. It did not load on Windows 7. We tried downloading drivers and doing everything possible to make it work. In the end we ordered a different adapter from another vendor and it worked right out of the box. We returned this one but ONBENE the seller refused to issue a refund. Very disappointed. I would not recommend the product nor the seller.
