Amazon have e-mailed me, asking me to review this product, purchased some months ago as a RAM upgrade for my ageing Sony Vaio laptop.
It's a stick of memory. It looks like a stick of memory, though since installing it, I haven't actually set eyes on it. It works silently, rather like a stick of memory, and it remembers stuff, which is what I thought it would do, but it tends to forget everything when the Vaio is powered off. It is then prepared to remember a whole lot of new stuff when it is switched on again. In this respect, also, it behaves like a stick of RAM.
Note the attractive, but not unusual, green PCB, with the decorative yet functional copper contact strip along one edge. This contrasts nicely with the delicately-printed grey modules neatly arranged in two lines of four. Aesthetically, this product cannot be faulted. However, as previously noted, it is invisible once installed - you may wish to take a photo so you can remember what a good-looking stick of RAM this is, and how wise you were to purchase it.
Like all computers, the Vaio will inform me if this stick of RAM is faulty, so we can safely assume it is working well. It is certainly working better than the dumb plank at Amazon who thought it was a good idea to nag customers into reviewing products that clearly don't need a review. This product is not SO DIMM as that person. (See what I did there?)
