My unit worked fine for about 3 months and then failed.  I'll return on factory warranty if I can find out where to sent it.

Failed bulb after 3 months intermittent use.
Works out at about $15/month which seems expensive in comparison with other bulb options.
I imagine the manufacturer will replace, but it's still a nuisance,

Both units I purchased have failed. They lasted for about 3 months. Based on their cost, there is no reason to return them.

This SD memory card reader was easy to use, but failed after 3-4 months.  It quit recognizing cards or said the disc needs to be formatted.  NOT recommended.

Started acting up after 3 months of minimal use.  Was no longer able to delete or create a new partition, causing Windows Disk Management to crash or hang.

I've been installing this unit for about 3 months now and the failure rate is high when using the ethernet in/out ports. One client within seconds of turning it on had issues with packet loss and timing out, another client had issues about 2-3 weeks after being installed, and other clients have had misc. issues, usually relating to packet loss again from in/out ethernet ports. One unit arrived with something rattling around inside (didn't install, sent right back to Amazon), one unit arrived damaged. Overall out of 6-8 units we've had a high fail rate.

It worked just fine.  Fast forward 3 months and apparently one of the capacitors inside leaked all over the circuitry.  Now it's a useless paperweight.

I bought this in February 2016 and it died completely in October. Supposedly this is warranted for 3 years but ASUS's customer support is so dreadful that it's impossible to even figure out how to initiate the return process. When it worked it was fine. Then it just stopped working quite suddenly (taking the entire USB bus of my Windows 7 PC down with it for company, requiring an expensive service call to repair).

As another posted mentioned here, I'm also using this for amateur radio purposes. Find something different, from a different manufacturer, because as good as this is supposed to be, when it fails you're up the creek without a paddle or a warranty. BEWARE!
