No problems so far. Flawless operation.
I installed it in a Lenovo T450, as a second hard drive, in the slot where the Sierra Wireless EM7345 LTE M.2 4G Module was, and there I installed the operating system (Linux). As for speed, I think any limitation now lies with the processor (i5 5xxx) and the memory (SDDR3).

Hello, the model of the 32GB.
I had bought it in early 2017, as a second scratch disk and also as a page file. I no longer use it due to an upgrade I made 3 months ago because of space, but I never had any issues with it, and it still says it has 100% health, probably because it has MLC chips.

Very cheap option, speeds as advertised (max potential), but many laptops in the early stages of M.2 2242 PCIe were not compatible, and also the initialization is not so easy for an inexperienced user (hence the 1/5 review type, who never managed to find compatibility with his laptop or activate it correctly). The disk is excellent for its price, without any problems (in general, it is difficult to have issues with SSDs, most of them occur during their lifespan rather than their functionality).

Bought in early December from the company's official website, the SSD is NOT compatible with all laptops with this port. Be careful what you buy.
Plays fine, normal disk initialization and speeds really at 480mb/s.
Reliable for its price.

The product never worked as it couldn't be formatted no matter what. I tried all possible ways (device manager, cmd, external applications, etc.) and always received error messages. I had it replaced at the store, but the new one had exactly the same problems. I returned it for a second time and got a refund.
