Used it one evening for a few hours. Did not use until today as second time. Hooked to 12v boat battery (small Gel Cell) and it burned out has  smoke in the inside, none out. It is a head light for a car I will get a brand name one  at wally world as the return date is past.

I ordered 5 of these "filament-type" LEDs.  One didn't work out of the box and another failed within 24 hours.  I return all 5 and got a quick refund.

It worked great the first time. I put it in the second time it died on me in a half hour

Worked great for the first 20 hours of use. Then the motor burned out suddenly during a cycle(the motor was smoking). I'm glad I was close when the smoke started, I'm sure the failure could have been much worse. I contacted the company about the problem, but they seem unable to support the product. I'm left now with a useless air compressor. I would be very suspicious of the reliability/quality of this system.

The lamp socket in mine came apart inside the first time I screwed a bulb in. Replaced the part at the hardware store, since it was less labor trouble than exchanging the whole light. But the sleeve for the bulb to thread into was hardly thicker or stronger than tin foil. Must have saved the factory two cents compared to a quality part.

Clogged and jammed modt printer. Some of the problem was multiple cross-wrapped filament on the roll, to get a print i had to re-roll it to another roll

I ordered two because of the price to have a spare. I needed it the next day because the first lasted 2 hours. The second, the filament wasn't even attatched. Don't buy these spend the money and get a GE bulb!

The included connector burned out within a few hours of use, lights also got really hot. I used the suggested power supply as well

Well I put the bulb in carefully made sure not to touch it, reset the hour meter on the projector and it lasted 24 HOURS!? Then it exploded...literally, smelt terrible then exploded.  what the hell? I wanted a projector lamp not a fricking IED.  So now I'm running the original bulb again with over 3800 hrs on it.  I wanted the replacement as a preemptive measure to avoid the bulb exploding...So much for that.

It worked like a charm for the first couple hours.  I used it for home brewing.  After that, everything on the digital screen lights up and stays that way.  Tried removing the battery and putting it back in....but it just defaults to everything lit up.  This is not worth the $18 it's being sold for.

I purchased one of these drivers at the local Costco. Second day, second use driving small wood screws into soft pine, unit just stopped, wouldn't turn. Returned to Costco for replacement unit.
Second unit, third time using it, again driving wood screws into pine, unit just stopped. Seems to charge o.k., but will not rotate, makes no sound as if the motor is just dead.
Oh well, I won't be getting a third unit!

The first time I print each day, I get a big black smudge.  After this is cleared, it works fine until it is not used for a few hours, and then it starts growing again.

This pen looks nice and worked for all of 30 min.  It will no longer feed the filament so it is useless.  Still working on return information.

I ordered two of these and was surprised at how dim they are.  I thought I could live with them as I only needed to see my way to a shed at night.  I could see enough not to trip over something but not much else.  Now I see that one of the bulbs has burned out after less than 10 hours of use.  Since I have to replace on I will be replacing both of them.

I bought this and used it for 30 mins and it failed.  The connection between the shaft and the motor somehow malfunction and the spool head no longer spins even though the motor spins freely.  I called BD and had it replaced through warranty.

I received the second unit through warranty.  It only lasted for a few days longer than the first one I received and then the same problem occurred.

This product will not stand up to any normal use period.  Too much fail here to describe.

Within hours of use in a track light, a bulb cracked.  I figured it was a fluke and replaced the bulb.  Unfortunately, that bulb also worked for a few hours and cracked.  I had to seek a refund, since two of the bulbs bulbs were almost immediately defective.

After 3 uses it won't turn on, is dead, the filaments has not even been washed. I can't use it.
