My first impression after receiving and opening the package is that the device itself felt sturdy, if not outright bulky despite its actual slimness, but it's well-built with a rather rough aluminum finish that seems to justify a product marketed as being 'premium'. It comes with a nice portable case that can fit the device and its cables, which is a nice addition to the product that I wasn't aware of when I initially ordered it.As my very first Blu-Ray drive, I am very satisfied with this item as it is capable of doing exactly what it says it can. I picked it over some other more reputable brands due to its affordable pricing and 4k support (although you need to patch its firmware first). By connecting it to my MacBook Air M2 (using the provided single type C cable, without needing an adapter or dual port connection like the Buffalo drive) and using the makemkv software, this drive can play (or rather when using this said app, extract) pretty much any Blu ray disc available - be it a regular 1080p BR, UHD (4K) BR, discs from any region or copy protection, bootleg discs, and afaik, even those with cinavia protection -at least in theory, as I haven't tried that many yet. They're also compatible with DVDs and CDs as well, and supports burning to all of these disc types. Since the app only does ripping and not playing, it is a good idea to have some external storage drives to keep these media for ease of access in the future.Despite being rather loud when in use and can be slow (up to 30 minutes or more when ring ripping a blu ray), I believe this Blu ray drive more than justifies its price. I've seen players twice the price that doesn't support half of these features (usually lacks 4k support and is fixed to a certain playback region/ has cinavia due to licensing requirements, etc.).Would recommend this external Blu ray drive for those who doesn't have any device to play 4k Blu ray discs yet (although cheaper/better alternatives exist for non 4k drives). It's affordable, does everything, and seems durable. The only ceveat is that there might be a lot to learn when getting started, especially when it comes to patching the firmware for 4k support and using makemkv - although this issue isn't specific to this brand/model, it's a generic software limitation for all such drives. However, many tutorials are available online and they are trivial to work with once you are familiar with it.
