very short life - not dependable

When this arrived the quiet setting did not work so I was sent a new one.  The second one did work for about two months and then it just stopped.  It worked all right when it did work but due to the lack of longevity and dependability I would not recommend.

I purchased these LEDs to replace G4 base lights on a timer circuit for an outdoor garden on the promotion that they have very long life span and wouldn't require replacement as frequently.  Within 1 month the first one quit working.  Now, about a year later, none of the lights are working.  The last one died last night.  These lights have a shorter life span that the halogen bulbs they replaced.  I was willing to have lower light bulb output as a tradeoff for longevity.  Clearly this is disappointing performance.

I purchased this item in December, 2014, and installed it upon receipt. I found it easy to program and use and it worked fine until today when it just stopped working. The clock still works, and it is still possible to set the program settings, but the unit no longer turns on and it does not pass electricity. So it is completely useless. It was used only indoors and well below rated capacity. It lasted just seven months and then died.

This unit is the right design and has the right functionality for my use. Unfortunately it is a piece of junk that doesn't last -- obviously super-cheap construction with low-quality parts that don't last very long.

I have contacted Hydrofarm about replacement under warranty. I have not yet heard back from them. I will update this review based on their response.

Update July 22, 2015: Hydrofarm replaced the non-working timer promptly and at no cost. Therefore I have revised my rating from one star to three stars. Customer service was excellent, but the unit should have lasted much longer than seven months. So far my experience is that this unit is poorly made and readily subject to early failure, but that the company is good about supporting the product if it fails during the warranty period.

Dies after less than a year, this one stopped working within 12 weeks.
Motion sensor just locks up and daylight sensor doesn't work, so it's just on, 24/7.
Same issue with 3 bulb version.  Get something else.

I purchased this light 22 months ago and it stopped working recently.  It did what it was supposed to do while it lasted however had it remained on 24/7 for it's full 30,000 life it should have lasted 3.4 years, which is nearly 2 years longer than it actually last.  It was activated on several times per day but by no means continuous.  Unfortunately the energy consumption of LDE bulbs is so small that the difference between having a bulb on all the time and having it on only when needed is very small.  Given the short life span I experienced I expect that the energy savings of these bulbs is negated by the material and energy used in manufacturer.  I must grant that it was used on an uninsulated front porch and subject to Minnesota's freezing winters and hot summers.  I will try a different brand on my next purchase with the hopes that I can get a bulb that meets it's rated life.

I had this since last year.  I used this as a portable power for my trimmer to trim my yard when I reached a farther place away my home power plugs.  I did this routinely about once per month. It worked fine for about 10 months for me.  However, a few weeks ago while I was again doing the regular trimming, this unit suddenly burst out smoke and stopped working.  Apparently that it had been damaged by short circuit.  Fortunately there was no explosion.  However, I am very bothered by the fact that it does not have an effective fuse to prevent such short circuit from happening.  Now the unit is partially burned.  I do not think it is reparable.  I need to contact my local recycle center to recycle it.  I expected that it should work for at least 3 years for me.  But its life span is much shorter than I have expected.

I purchased this scale in January of 2012 from Amazon.  Today, February 2016, in finally died.  I gave me a "Lo" battery indication and three sets of new batteries failed to resurrect it.  Looking back it did go through batteries quickly and the auto-off feature would interrupt weighing of sequentially added ingredients to recipes (touching the scale every 20-30 seconds keeps it awake). Disappointingly short lifespan. I would not consider the same one to replace it.

Had this drive for a very short period of time before it started making loud noises and stopped working.  this is the 3rd one to die this year alone.  if your data is important to you buy some other brand.

Well we have had two of these same models in 2 years. Each of them quit working within a year. So we are looking for a different brand now. Good luck with this one. Worked well for a short time.

We bought these in November 2017, and after less than 3 months, 4 of them have gone bad. After a few weeks of working fine, a bulb will begin rapidly turning off and on as if they are burning out. The first one burned out within a month. Since then, 3 more have burned out in different fixtures in different parts of the house. We have several different types of LED bulbs in the house, and this is the only one that has had this issue. It is unfortunate, because they are attractive bulbs with a bright warm light. If they lasted, we would be very happy, but due to short lifespan, we won't be buying this bulb again.

This was a very fine VCR when it worked, but it stopped powering up after just 4 months of occasional use.  It's completely dead.  The warranty is only 90 days, so I have an $80 paperweight now.  I noticed some other reviewers complained of the same (unfortunately, those reviews came after my purchase).  Beware, as quality on this VCR seems hit-or-miss.

This lamp is great when it works, but it has a very short life span.  The light went completely out after just over six months of use.  I've owned three of these so far and all of them seem to have a life span of about six months.  Also, what makes this matter worse is that they do not offer replacement light bulbs, so I have to buy a whole new lamp every time.

I bought this LED light bulb to replace a halogen light bulb that requires a replacement once a year.  I thought this LED will stay up there working for years and will save on energy as you'd expect from LED.  Well - the first one died just three weeks after installed.  The second one turned dim and stayed dim a  week later.  The third one started blinking on/off violently for about an hour and then died - again, just a few weeks after installed...

it worked ok and it will die after a year or so.... Don't last long. I will try another brand....

Worked great while it lasted. I only gave it a full charge maybe 3x and then it wouldn't turn on. Oddly, the led would turn full brightness on when I charged it on the 3rd time. Then unplugged from charger, it was a complete dud! I think it should have lasted longer than 6 months. I'll have to find another manufacturer and hope for the best.

Although bright, all four of these quit working after 4-6 months.  The bulb is not replaceable, as it is soldered to the circuit board.  The back of the circuit board was black, so something on it overheated and burned out.  Consider these disposable, for short term use.  Not recommended.

First off, this is a great little speaker system. It has excellent sound, even at a high volume. I use this to play music for my pets while I'm not home and at full charge it will run for over 8 hours straight. I'm only giving this product 2 stars because of it's lifespan. I have purchased 2 of these in the past year and each have only lasted for about 6 months each. Both of my units completely died (as in will not charge, turn on or play anything) in under 6 months. This particular one only lasted 4 months. I will say that I ran this unit for 6-10 hours a day approximately 5 days a week during that time, but for a rechargeable item, this should have lasted much longer. It doesn't have a warranty and I can't return it to Amazon.

Don't buy this product if you intend to use it a lot. It's probably fine for playing music for an hour or two a day. Very disappointed.
