First, I have to say that delivery and tracking are much better than other Chinese online shops. Quality of some items is excellent. Some not so much. Wi-Fi control switches all seem great. Mechanical parts: Website has a clear picture but an incorrect substitute is sent. Argued and got a refund. Have reordered after being assured that the product will be the same as picture. Here's hoping! Arriving soon. Outside lights: A few work well but in the same batch, some are dead, some flash on and off even in daylight, some work for a few months then stop. Over all, not so good, 50-50. Tools: most are OK but not premium. Most function well. Bearings are junk. Diamond hole cutters are excellent for the money. The whole site is a mishmash of good thru not so good. Maybe rate 75% over all.
