As for order - Good, no issues with delivery (probably thanks to ASS 0045 as we call it here), normal delivery time. As for seller him/herself - good prices, fast response. [I'd rate customer experience as very good] As for products itself - well... not sure if i Can 100% reccomend. Those modules have bigger "lag" than other brands, and after few months of using those devices they started turning on and for a second off in random times of day. For price i paid i may expect small issues like this rarely. Definitely not a seller fault because my friend have same issue with same product from different seller. Fortunately resetting and readding devices helped [and seller tried to solve problem and be helpful] - software issue is not a seller fault but manufacturers quality of code and lack of testing/quality assurance]
