This was supposed to be a refurbished product, but did not work at all. Tried on 3 TVs. Returned to amazon.

Mine arrived DOA, never worked at all. Tried several different power sources, different arrangements and never got it to work.

Read good reviews about this unit, was very excited to mount it to my living room TV for netflix/media streaming. Ended up DOA, I tried three different kits of RAM on it and nothing would get it to POST. It turned on, fan spun at full speed and nothing much else happened. I suppose it would be good if it worked, but I'm not trying another one.

Arrived DOA. Save yourself time and effort, just go to Harbor Freight and pick one up for less.

Came DOA. Wouldn't light up. After pressing the power button a few times, the button stopped working too. couldn't return as I hadn't opened the box for a month after receiving - by the time I opened and found it was defective the return window had expired.

Item was DOA.  Battery wouldn't hold a charge long enough to do anything and it wouldn't operate on AC power.  Maybe I got a lemon, but not willing to play the shipping tag game to get a functional one.  Returned for refund.  Amazon refunded without question.  A+ for amazon.

My item arrived DOA and I am initiating a return for refund. I bench-tested the unit with a regulated power supply and known-good ground, and it did not deploy. I used both ground wires individually and then together, to be certain that this was not a factor. I hooked it up per the instructions.

My power supply produced 12.36VDC regardless of load in this test (hooked directly to the test bulbs), so I was able to rule that out as well. The end result was this would not switch on either 12v test bulb (tried both incandescent and LED to rule that out as well). I had high hopes for this, but despite the QA label affixed to the back, I suspect they're not batch-checking very many units.

I received the product and out of the box refused to turn on even after trying.

very disappointed the unit did not work right out of the box, I tore up box prior to trying out my mistake, but not happy.

It was DOA so was returned for a refund, something I should add Amazon excelled in with its excellent customer service.

Bottom line, it was a no 1 disappointment so cannot be recommended.  You might be lucky and buy one that worksd, or you might mirror my experience.

BTW the one star rating is more than it deserves!

Didn't work out of the box.  Cheap garbage- do not buy.

Item was DOA, however I did not attempt to use it (it was a spare backup) for over 6 months before finding out. Shame on me for not testing upon arrival; but as I understand the policy, it would not have been eligible for return anyway?

This product did not work. Came DOA. When I plugged it in, it just clicks for about 5 seconds and stops. Then the bulb indicator light on top flashes red.

I've already called for a refund!

DOA but thank you Amazon.  They stand behind what they sell and gave me a full refund.  That's why I shop Amazon!!!
Seemed to have an electrical issue since no matter what I did, it would not fire.

DOA. After I put it all together, there was no response on power-up. All the other parts (PSD, RAM, CPU, ETC) worked with another board, but this one was dead out of the box.
