Pros: This toner is the original but you still can fool the printer into taking a toner that is not original or a toner that is not actually empty but still has several hundred more pages of toner in it.

Cons: The printer likes to call for toner too early before it is actually empty

Overall Review: As some of the previous reviews have already talked about, the printer has a built in toner change meter. In order to fool the printer into taking an old toner cartridge before it is actually empty and needs to be changed, you must first select the Menu button of the printer. Then select General. Then select Replace Toner. Then choose the down arrow and change the selection from "Stop" to "Continue". Then press the OK button. Then change the toner or actually just pull the toner out, shake it and put it back in again. Then press the OK button to continue. Your printer should accept the "old" toner as new and allow you to continue to use it. You may also have to press the green "Start" button on the printer 7 times to get around the message to replace the toner as stated by a previous reviewer.

Pros: looks just like an official Apple adapter with all the normal markings

Cons: didn't work out of the package. It caused a delay on both the iPad and iPhone 4S. When attempting to play video, nothing appeared on the 55 inch Samsung. An error popped up on every video stating "Cannot Play Movie The connected display is not authorized to play protected movies." This is with every video including the free 1 minute previews. Also the connecter heated up after a short while so I think it has a short due to rust or water damage.

Overall Review: I am sure refurbished means different things to different people depending on your experience. I usually do fairly well with refurbished hardware. This product has seen water damage and I don't think it can be easily fixed.

Pros: I bought this in 2017 hoping for a reliable storage device.

Cons: I don't recall using this for anything before now. However, it doesn't appear to be recognized in any device as a functional MicroSD card. If I had anything stored on it, it doesn't appear to be recoverable. Waste of money. Do not buy this one. I have better luck with SanDisk.

Pros: Small and ergonomic. Plenty of buttons that I won't use. Works great with the new HP Stream 7 tablet that has Windows 8.1 and Bluetooth.

Cons: nothing that I can think of right now

Overall Review: The little power on off switch is next to the laser. I am always a little nervous that I am going to look into the laser when looking for the switch to turn it off. I also don't know how long the batteries will last but I am hoping for the best.

Pros: includes 2 DVI 1 HDMI standard (not mini) and 1 Display port that can be converted to DVI with appropriate cable. Price is right after rebate. relatively quiet

Cons: large sized card but not much more than about 9 inches. takes 4 power connections into the 2 6 pin connectors but that is standard these days I found out.

Overall Review: I have many years experience in the computer building area but I am a bit of a novice in this area because I never spent more than 100 bucks on a card before. I am very impressed with the game play at this level. I plugged it into my 55" Samsung LED TV and started up Crysis 2 with DX11 Tessellation pack plus hi res enhancement pack. At 1920x1080p the picture and sound are incredible. I can't wait to try some older games like Half Life 2 and see how this card does compared to my older Nvidia cards. I am using an AMD Phenom II x6 1090T Black and 20GB GSkill Ripjaws RAM on a MSI 890GXM-G65

Pros: portable size-works with most aircards with firmware-indicator lights are helpful-works on ac adapter if you want to use it indoors but remove the battery first to save it for portable use only

Cons: battery life is not very long-instructions are not low tech user friendly but most good techs should be able to figure it out-air card sticks out making the unit a little large overall. I can tuck it into my pocket and let the air card stick out. I just have to be careful not to break off the USB that is on a swivel.

Overall Review: I use 2 of these. One at home for travel and one at my office. I just take the air card back and forth with me. I would use this on the train but the battery life is limited to maybe a couple of hours. You can firmware the device to accept whatever air card you like. I use the Verizon 4G LTE and it works great. I have the CradlePoint Sprint PHS-556 but I loaded the Verizon firmware onto it. I could always change it back to the Sprint firmware if I want to but it's working fine this way.
