Pros: works fine as expected. The reason chose this product is for compatibility of my DDR previously occupied in my PC. I added two more module for increasing main memory from 4G to 8GB.

Cons: Price is somewhat expensive compared to 8G module - almost same price. I know this DDR chip already had bit crossed to bigger size chip but from the consumer point of view, it is expensive.

Overall Review: Spending 10~20% more cost would have same memory size of 8GB with throwing out old 2x2G modules. But market already started to move DDR4 and this DDR3 module is less likely to be usable on my next PC upgrade.

Pros: - hardware spec and performance is generally good, especially 4k screen and gaming performance.

Cons: - system crashes (blue screen) very often, mostly when plugging USB-C cable for extended monitor - extended monitor screen became all blue, which happens very frequently. - audio device is disappear and no more sound, which needs power cycle.

Overall Review: - this product needs many bug fixes for audio and video control, which requires system restart very frequently. - I would not recommend to one who want to use additional monitor.

Pros: hardware works fine

Cons: I don't think software maturity is not for sale yet. Product was delivered today and I spent only several hours for installation. I'll spend couple of days more to figure out below failures but I cannot stand why I need to spend my money and my time to debug this bad product. (Actually I need to use IP camera ASAP). - WiFi doesn't work when LAN cable is plugged out meanwhile software tool says that. - Chrome browser cannot open the camera screen. M$ Iexplorer works. Didn't test firefox. - During opening camera with Chrome, it asks installation of another SW tools, which installation package shows only broken charaters. I'm wondering if this company tested even English Windows platform. - Capture folder setting doesn't work. So no capturing is possible. - At the very beginning, system time was 1970-01-01 and it won't be changed even with network time or PC system time. Now it is changes somehow.

Overall Review: Probably I'll refund couple of days after if all above issues are not solved. Think about why people buy popular brand instead of never-heard of chinese company.
