This review is from: BYTECC Bracket-35225 2.5 Inch HDD/SSD Mounting Kit For 3.5" Drive Bay or Enclosure
Pros: Does what it says. However, read the "cons".
Cons: Any drive you stick into this will 1) not sit flush to the back of the bracket and 2) will be centered. So if you're planning to use this to mount hard drives in external cases or JBOD enclosures, it will not work since the connectors will not be in the same location as it is for 3.5" drives.READ FULL REVIEW
This review is from: Soleus KY-80 8,000 BTU Portable Air Conditioner
Pros: It's fairly compact. Lowes carries this model nation-wide, and it's actually about half the width of the size of the box it comes packaged in. The hose is easy to connect to a window, which literally takes me about 30 seconds to attach every time I want to use the AC. That was the main attraction for me: I did not want a window unit that would have to hang out the window since I need to remove it and close the window each time I stop using the AC. If you are expecting to use it as a personal 'fan' next to your desk, or to cool your small bedroom/dorm room, it's a good deal especially since you can find it on sale for about $200 in most places. It can also be easily returned to your local Lowe's or Home Depot (as of 2013).
While the unit can certainly blast cold air at a good volume, it does have a hard time lowering the temperature room-wide (108 sq. ft.) We've had temperatures ranging from 60F to 90F in the past two months that I've owned this AC. When the temperature is 90F outside, it can lower the temperature inside from 85F to 78F in a little over an hour. When the temperature is 75F outside, it can lower the inside temperature from 80F to 74F in under an hour.
Cons: The lowest temperature setting on this AC is 61F. There are a few issues. The first is the obvious: it is a one-hose AC, which means it creates a negative pressure in your room. It needs to suck in air to cool off its radiators before it blows the hot air out of your room, and since it doesn't have a secondary intake hose, it sucks the surrounding air from within your room. If your room is air-tight, the AC actually has a had time cooling down. You need to have air coming in from somewhere else, such as a hallway, window, etc. It needs that air circulation to keep cooling itself. And you'll notice it sucks up A LOT of air, even on low settings. So you'll be pulling in hot air from the rest of your house (for example, from underneath the door cracks or the central air vents), which explains why the AC cannot cool a small room down below 74F (even when the outside temperature is a cold 60F). But there aren't any other options since it will start to struggle if you create an airtight room.
The second issue is also a bit obvious. The venting pipe and window mount aren't airtight. There are gaps all over the place. So the hot air coming out of the AC will vent back into the room in small amounts. I've read that other people have reinforced these gaps with tape, which helps resolve the issue. Some people add foam tips and tape the plastic to a certain length to cover all the gaps, but I just shove a towel up against the plastic when it's mounted on the window to "cover" any small gaps. However, the venting pipe can get quite warm, and it feels like a heated radiator if you hover your hand next to it.
The third issue is the low water drain coupled with the weight. I've only had to drain the AC twice in the past month that I've used it (I use it 4 hours a day in 40% to 80% humidity), but it's a chore. The drain plug is only an inch off the ground. If you have carpet, it's impossible to wedge anything underneath the drain. The AC will refuse to run if the water reservoir is full, so you must drain it. The only way to do it is to drag it to a water-safe area (outside or floor drain), or to lift the entire 60+ pound machine up onto a table or tub and drain it. Even with the stopper in the drain plug, if you tilt the entire unit too far, water starts to leak from an unknown place.
The fourth and final issue is that the fan inside can easily scrape against something inside if the unit isn't level. It's usually rather silent, except for the huge gust of air it sucks/pushes. But if you leave it on uneven carpeting (more than 1/4th inch off level), you can hear scraping sounds inside until you level it out.
This review is from: HAWKING HAI7SIP 2.4GHz Hi-Gain Omni-Directional 7dBi Antenna
Pros: I have a TP-Link TL-WDN4800 WiFi PCI-e 1x adapter in my desktop. This wireless card is fairly expensive, sometimes up to $70 if it's not on "sale". It comes with three external antennas. I also have a Apple AirPort Extreme wireless router. My PC sits three rooms away from the router, and it gets a fairly good connection at -63dB. For your information: Anything between 0 to -30dB is considered excellent, -30 to -60 to be good, -60 to -80 to be passable, and anything past -80 is considered unreliable by most WiFi 802.11 2.4Ghz standards. I wanted an improvement, so I purchased a Hawking external antenna to replace one of the three antennas that are on my WiFi card (since the Apple AirPort Extreme cannot support external antennas). The results were noticeable, but not by much: using inSSIDER to run a benchmark test, I was connected at about -59dB on average. That's an improvement of 4dB, which is fair given the specifications on this antenna. It really doesn't give me a "more solid" connection, or faster bandwidth. However, the product does what it stated it would; give me up to 7dBi gain depending on configuration. Also, I went from seeing 6 other WiFi connections from my neighbors to now seeing 11 other WiFi connections, so it's definitely a noticeable difference. However, you should probably look for a higher gain antenna if you are trying to fix a non-existent connection. This antenna provides minimal gain.
Cons: Minimal gain of only 4dBi when connected to 802.11G 2.4Ghz with antenna on client-side.READ FULL REVIEW
