APC BACK-UPS RS BR1500 1500VA/865W UPS System Review

Average Reviews:

(More customer reviews)This item is BR1500, which also called RS model vs. the BX1500 called XS models. External battery BR24BP can be used for both BR1500 and BX1500. The capability to connect external battery is great, since that can help reduce the downtime when California experiencing "rolling black" in the summer.
There are basically 2 differences between the Back-UPS RS(BR1500) and the Back-UPS XS (BX1500) models besides their names.1. The Back-UPS RS models have both 1-line 2-wire phone/fax/modem data-line protection and 10/100base-T ethernet protection, where as the Back-UPS XS models only has 1-line 2-wire phone/fax/modem protection.
2. The Back-UPS RS models have both Boost* and Trim** as features of Automatic Voltage Regulation (AVR), where as the Back-UPS XS only has Boost. When the input voltage increases above the high transfer point of a Back-UPS XS model it will only go to battery.*AVR Boost: The UPS is compensating for a low utility voltage. While the UPS can run in this mode indefinitely without any negative impact on the UPS, the circuit should be checked by a qualified electrician if the utility voltage is consistently low.
**AVR Trim: The UPS is compensating for a high utility voltage. While the UPS can run in this mode indefinitely without any negative impact on the UPS, the circuit should be checked by a qualified electrician if the utility voltage is consistently high.
BX1500 does not have the AVR trim feature, when AC line voltage is higher than spec, it will switch over the battery power till the line voltage drops into the spec range.
Please note this is called "backup UPS", not the "smart UPS" line. Backup UPS does not produce pure sine wave. When power lost, it will take some milli-seconds to switch over to battery power. "Smart-UPS" produces sine wave and the output AC was from DC source all the time. When AC input lost, the AC output will not have any interrupt.
For most computers, the "backup-UPS" is good enough, since the power supply inside PC always have capacitors that can hold for about 100MS or longer. When "backup-UPS" switched over in about 20MS, the computer will continue operates without much impact. But for A/V equipment, this may be an issue, especially the output is not pure sine wave. I would not recommend use this UPS for A/V equipment.

Microsoft Wireless Media Desktop 1000 (Black) Review

Average Reviews:

(More customer reviews)Prior to getting this, I have been using a Dell provided Bluetooth keyboard and mouse, made by Logitech I believe.
Which means I'm probably a little spoiled for wireless products. The only fault was that the battery life was a bit less than I would have preferred. Indeed, I was also intrigued by quiet typing and water resistance claims. So, I took the leap and got this Microsoft set.
First the bad. The mouse is worthless. Really is. I've gotten used to the side buttons and other features of my present mouse. This mouse has the two buttons and a scroll wheel. The two buttons work okay, but the wheel makes for entirely random scrolling. It does not keep a steady speed, has no relation to the mouse setting in windows, and the average speed of scrolling is immensely slow, only a couple of lines.
Add this to the fact that affects both mouse and keyboard. The wireless connection is rather disappointing.
This set comes with a receiver that plugs into a usb port. The receiver is needlessly designed to look like an interesting addon. It is about the size of two mouses put together, with green lights on top that light up when connected. I'm a bit bothered by all the little lights computers seem to insist on and this just makes for more bother. If you could hide it, that might be okay, but the signal isn't strong enough. I have it right under my monitor and still get popups saying it has lost connection. It was really bad with the mouse, but still occasionally lapses with the keyboard, that is a foot away.
Any obstruction causes more problems. A real hassle. And adds to the general imprecision.
The keyboard itself is nice. The key noise really is significantly quieter. I've not tested the water resistance, but am comforted that it is there. The layout is a bit wider than other keyboards I've used, making for an initial bit of transition as I have to reach a bit farther for the higher keys. Those with smaller hands might find it uncomfortably wide. The programmable and media buttons are certainly handy, making for really quick access to programs that might not be always within an easy click.
Yet, I'm not sure such ease overcomes the deficiencies. I've already gone back to my bluetooth mouse. Now I'm using two usb ports for mouse and keyboard, a situation that may not continue and may get me to retire the microsoft keyboard as well. Which is sad. I wanted it to work better, but am ultimately frustrated by the wirelessness of the wireless.
It's not too costly, but the frustration it brings might justify either a little more money to get a setup that can be used without frustration, or invested in a non-wireless combo that provides all the functions without any batteries or bother.
