Pros: Accurate. I have two of them and they agree with my more expensive brand-name one. A nice IR thermometer for the price.

Cons: Laser aim point on both units is a few degrees below the actual aim point of the IR sensor. At about 12" from the target, the red dot is about .5 to 1" below the IR aim point. At 8 feet, it's about 6" off. You can compensate for it, but it renders the units imprecise and makes them difficult to use for measuring component temperatures on a crowded PC board. My brand-name unit is spot on, so this appears to be a design or construction flaw in the Rosewill thermometer housing.

Overall Review: These are accurate enough as long as you do not need to aim them at a small spot.

Pros: It is tiny and it works as an extremely slow and very basic Windows PC.

Cons: BIOS power-on settings do not work. MLLSE PC has no documentation. Machine is extremely slow.

Overall Review: Just say no. For just a bit more money you can buy a much better mini-PC that works properly out of the box. While the small form factor is nice, the hardware has problems not found in other devices. If you need a PC that stays on 24x7 and comes back on after a power outage, this one fails.

Pros: This would be a decent modular supply but the non-working fan circuit renders it unsatisfactory.

Cons: The fan spins at full speed under no load with the ambient air temperature at 68 degrees Fahrenheit (20C). The inlet and outlet air temperatures are both at 68 degrees, but the fan does not slow down. On the bright side, the 140mm fan is pretty quiet at full speed compared to a 120mm fan...

Overall Review: This unit is powering an i3 4150 system with integrated graphics, so it is not being stressed in any way. The assemblers could exercise a bit more care when inserting the wires into the motherboard plug, as they are badly tangled. This makes it hard to create a neat bundle. I realize this is a trivial problem but for those who care about the neatness of the final build it is slightly annoying.

Pros: Very well built, high quality case. The fan controller works well, the fans are reasonably quiet, and the sound dampening is very effective. Plenty of room for cables on the back side and the holes are located right where they should be for neat cable management. Plenty of room for hard drives and optical drives.

Cons: The case allows mounting two SSDs flat against the back side by providing eight holes under the motherboard. This makes for a neat installation, but you have to remove the motherboard if you need to swap out a drive later. They could include two brackets to hold the drives.

Overall Review: I replaced a Silverstone Fortress FT02 with this case because the FT02 was too large for the space I had available. I was surprised at the amount of room in the R4, even in comparison with the cavernous FT02. The R4 has a smart layout that makes good use of the available space. The FT02 cools a bit better but the FT04 is more compact and is an excellent case for almost any build. You can add extra fans and the case has plenty of room for a radiator at the top. My case arrived with a little scratch on the door. The Fractal Design support team answered my email the very next day, asked for a photo, and shipped a replacement without any fuss. I'm usually not very impressed with tech support but their team is on the ball.

Pros: Seems to be a decent enough battery with adequate capacity. Will just need to see if it maintains a charge and if it lasts.

Cons: Contrary to somewhat confusing product listing, this battery does NOT come with its own charger. It acts as a charger for other devices, but you need to use your existing USB charger or a USB port on a computer to charge this battery. Charging takes a very long time using a standard 500mA USB charger or PC port.

Overall Review: Purchasers should understand that high-capacity means that you can get more charging time out of this, but not more charging current. The maximum charging current per port is 1A. The rebate process is ridiculously nit-picky and leaves grave doubts that a purchaser will actually get the rebate. They even go so far as to insist that you cut out and attach a tiny, almost-unreadable, printed address label to your envelope. Follow the rebate instructions to the letter and copy your forms and envelope before mailing. Ridiculous rebate requirements are apparently designed to deter purchasers from applying for the rebates. In addition, they promise to expedite your rebate if you give them a dollar of it back.

Pros: They look nice enough.

Cons: They have to be the absolute worst speakers I have ever heard. The left channel audio is about 50% of right channel and they distort at even very low volume settings.

Overall Review: The quality of these speakers is incredibly low. I recommend that you consider almost any other speakers instead of these.
