Pros: SPEED... mine is effectively class 15! After using this for a week in my phone...Read: 18.3 MB/s, write 15.0 MB/s -- Check Flash 1.16 (Duo core 2.1 GHz/Win 7.64). In my Motorola Droid 1 (A855): via USB = 2.65 MB/s w/Check Flash, via Droid standalone = 2.64 w/Droid speed test (Market app). This is as expected; Droid is internally limited. PRICE... cheap for its capacity and speed!

Cons: None

Overall Review: Original Droid class 2 SDHC: via USB = 1.9 MB/s w/Check Flash, via Droid standalone = 1.5 to 1.9 w/Droid speed test. I was hoping for some speed boost with my overclocked Droid (1.1 GHz) and I got a little, but it's real usefulness will be in my Canon G10 camera.

Pros: Works great! 3600 Timings not OK for MSI x470 (6.6.2020 bios) with x2700, but got 15-15-15-36 A-XMP without tweaking. I don't usually like RGB, but this looks great too. And cheap too boot. Will move to B550 when I can get 5600x.

Cons: None so far.

Overall Review: I would definitely buy this again. Superior brand and expecting overclock in it's upcoming B550/5600x home. * I don't suggest using Newegg's free shipping - it took 3 weeks to arrive. 3 weeks in the US. *

Pros: +Relatively inexpensive at this time. +Seemingly effective. +No defects detected.

Cons: -Shipping was very slow. -Wish they were certified.

Overall Review: *If the price is OK for you and you can wait for slow delivery, then buy them.

Pros: Relatively cheap! Often it's hard to get one for near stated pricing. The OS is stable, gets frequent updates and fits the device perfectly. The Pi 4 model handles 64 bit software just fine and allows me to run code I otherwise wouldn't/couldn't. The updated hardware (USB and Ethernet) was a key point over the non Pi 4 models as most of my projects are network based. And... it's reliable!!!

Cons: No cons. But it's not for everyone... Not all will like the inherent limitations of a small computing environment.

Overall Review: The price was right and delivery was fast too boot. I use FLIRC cases because they are passive heat sinks too. With those cases, I don't use the included ARCTIC Thermal 1.5 mm pads, but actual ARCTIC thermal paste.
