[EX Q]: Arrived ontime, but did not last long. Work fine for a little, but not long after, the part that connects to the computer separated already. I have aways been gentle when pulling it out.

[EX Q]: Great product, easy to install just plug it and start using it, beautifuly soundless. I use it to work enhancing photos with Photoshop. When cleaning a photo from dust or scratches I need to click many times in a row so when using a standard mouse the click sound becomes very annoying.<br />I am editing my review, because the roll wheel broke after 6 month of use. I opened the mouse to see what went wrong and one end of the axis of the roll wheel is less than 2 mm in diameter and made of plastic material, so easy to break... this is a design flaw.<br />Do not buy it...you'll waste your money just as I did.

[EX Q]: I have been using Thinkpads almost every day of my life since August 1999. I started with the Thinkpad 600e, then the T30, then the T41, then the x61 tablet, and now I have an x220 tablet. I have owned docking stations for 3 of them. I'm a pretty loyal Thinkpad customer. I have a lot of experience with Thinkpad equipment, and my current and last Thinkpads were Lenovo-branded.<br /><br />I ordered this AC adapter because it appears in the picture to be a genuine Lenovo Thinkpad adapter. It does not behave like any OEM Thinkpad power adapter I have ever used. I received it yesterday (very, very fast shipping) and started using it today. When I plugged it into the wall, it sparked. That has very rarely happened other Thinkpad adapters I've used, and usually due to international travel. I didn't think too much of it though.<br /><br />I only got my laptop up to 80% charge when I smell this horrible smell: it smelled like burning fish! I started worrying that my oven is on fire, so I got up to check on it and my foot brushed against the transformer on this power adapter. Burning. Hot. The smell is coming from the adapter! And feeling the cable on it, it almost feels melty. Not good. I pulled the plug from the wall and filed for a return right away.<br /><br />Save yourself the time and trouble and don't bother with this. The one from Lenovo is twice the price and it's worth every penny of not having the worry of burning your house down!
