Most Favorable Review

Better than I expected

Acer HN274Hbmiiid Black 27" Full HD HDMI WideScreen LED 120Hz 3D Monitor 300 cd/m2 ACM 10,000,000:1 w/Speakers & 3D glasses
Acer HN274Hbmiiid Black 27" Full HD HDMI WideScreen LED 120Hz 3D Monitor 300 cd/m2 ACM 10,000,000:1 w/Speakers & 3D glasses

Pros: Low crosstalk (ghosting) in 3D. High brightness is nice for movie-watching and gaming. Also works with the newer (and slightly better) 3D Vision 2 Wireless Glasses from nVidia. Unlike line-interleaved (i.e., polarized) 3D monitors, text can be seen just fine. If you want to use this with molecular visualization, make sure you have a pro GPU card (e.g., Quadro).

Cons: Since the resolution is the standard 1080P, at this 27" size, it corresponds to a pixel pitch of 0.311 mm which is way too big for my taste to do actual work on it (text use). But for games and videos/movies, it is more than adequate. As with most 3D monitors, it is a little darker than one would like in 3D, and the glare from the back (reflecting inside the glasses) will haunt you if you have a bright wall or lights behind you, as with all active shutter glasses.

Most Critical Review

Mine is useless

INEO I-NA217U Plus USB 3.0 to SATA 2.5 inch External Hard Drive Enclosure w/Built-in USB 3.0 Cable
INEO I-NA217U Plus USB 3.0 to SATA 2.5 inch External Hard Drive Enclosure w/Built-in USB 3.0 Cable

Pros: Cheap, buit-in cable, nice design.

Cons: Keeps loosing USB3 connection with an HDD in, and doesn't work at all with an SSD.

A mediocre toy

Syma X5C Explorers 2.4G 4CH 6-Axis Gyro RC Quadcopter With HD Camera
Syma X5C Explorers 2.4G 4CH 6-Axis Gyro RC Quadcopter With HD Camera

Pros: It was cheap on sale.

Cons: Unstable, almost impossible to trim even indoors, as it keeps drifting in one direction, then you move the stick to the other direction and center it, land it, lift it again, now it starts drifting in that direction. If you want something that you can lift and it will hover stably like a parrot drone, this is not it. Terrible camera. Although the resolution says HD, the noise level and the compression artifacts are so bad, the images and videos are virtually unusable.

Overall Review: If you want a cheap toy that flies, this may fulfill your need. If you are thinking about this as your first entry-level quadcopter for taking pictures and videos, do not waste your money with this.

Nice

ASUS VG Series VG23AH Black 23" 5ms HDMI Widescreen 3D LED Monitor 250 cd/m2 ASCR 80,000,000:1, IPS Panel, Height & Swivel Adjustable with Speaker and 3D Glasses

Pros: Cheap. Decent 3D. Nice colors. Brighter than Acer HN274Hbmiiid in 3D. Quicker (and less problematic) 3D (e.g., You can use Opera browser to look at 3D pictures from phereo.com and choosing Interlaced), since it does not need to "switch" modes like active shutter products do. You can use it for molecular visualization without needing a pro-GPU such as Quadro line, since almost all software support row-interlaced mode.

Cons: More ghosting (crosstalk) than nVidia active shutterglasses (Acer HN274Hbmiiid) in 3D. The parallax-lines are visible when you're using it as 2D regular monitor without glasses if you are not looking at it dead-center. The loss of resolution to half in 3D is significantly noticeable, especially if you'll need to look at text-containing content or see small/fine details, but it's fine for watching 3D movies.

Nice

AirCare 2-1/2 Gal. Capacity 2600 Sq. Ft. Mini Console Evaporative Humidifier
AirCare 2-1/2 Gal. Capacity 2600 Sq. Ft. Mini Console Evaporative Humidifier

Pros: Humidifies better than ultrasonic ones (usually referred to as cold mist) and doesn't create white dust everywhere like them. Doesn't have the boiling noise as I read about the warm-mist ones. Fairly quiet at setting one.

Cons: The big fan has become slightly unbalanced, so it generates a low-frequency hum now due to vibrating. If I may fix it, great, if not, it may become bothersome. If you need to run it at its highest fan speed (which I doubt), it will be quite noisy.

Overall Review: We owned three different ultrasonic cold-mist humidifiers over the years, and although you can see the mist coming out of them, and this one is completely invisible (because this one distributes evaporated water, instead of pulverizing water droplets into air), this one raises the humidity better (measured by an independent device).

Stay away from this lens that takes blurry pictures

Pros: Reach.

Cons: Terrible image quality. Even placing my camera on a tripod, using a fast shutter speed, and meticulous focusing could not save this lens.

Overall Review: I compared this to my Tamron 18-270mm zoom, and if you take pictures with Tamron at 270mm and recrop them to give you a picture equvalent to 500mm, it was still sharper than the images this lens took. Tamron also has the image stabilization, of course. Even for the cheap price, I would not recommend this lens since the pictures you'll take will be unusable, due to all of them being too blurry.
