Example input: I was very surprised at the high quality of the stitching, the sturdiness of the handles and the padding for my laptop. The price is amazingly low and the look is very good. I am quite happy with this purchase. It fit my MacBook Pro perfectly, with a little bit of room to spare.

Q: It worked very well in the first month. After about a month, it started to give problem with wireless signal and connection keeps dropping. Disconnection became more and more frequent until it reached to unusable state (3 seconds connected, drop, get connected again for 3 seconds, drop). Upgrading firmware didn't solve the problem. Tried installing OpenWrt and still not working. My conclusion is hardware issue. Called up the support to complain about it and, after three calls, they agreed to fix the router and said it would take 2 months! I stayed away from TP-Link since then. Worst home networking nightmare to me.<br /><br />Pros:<br /> Cheap.<br /> Rich in features.<br /> UI is quite nice.<br /> Signal is strong.<br /><br />Cons:<br /> Hardware issue as mentioned above.<br /> Poor support/service.<br /><br />Conclusion:<br /> If you MUST buy this brand, just hope that luck is on your side.
