I have some concerns with these new-launched products, but the pre-sales service gave me much comfort, my sales manager was very kind and patient, he knew products well and was able to give suggestions for landings.

This is my first try to buy from here and it's an amazing experience. The product is cost-saving and I met the free postage requirement, so I bought it with free shipping. After receiving it, I couldn't wait to have a test to see whether it has the capability to play a role in our company's phone system, It turned out a surprise, it works very well without any problems. Recommend.
