Unacceptable performance. Poor quality control or design.

I ordered 2 pair of these bulbs. One bulb failed after a few days of light use. Another has worked intermittently. GE better do something about their quality control or design of these bulbs. This is unacceptable.

Cool idea but poor performance.  Ended up being far too much work with inaccurate results.  Had to return it as it was distracting me from my game.

What a mess.  I bought this through Amazon Prime Now a couple days ago and am sending it back today.  I was surprised how poorly my fan performed given all the positive reviews.  I suspect mine was dropped some point after assembly or in shipping somewhere.

The unit I received was very unsteady on its base.  I triple-checked my base assembly (which is simple) for anything misaligned, and made certain that all screw holes were flush and even.  It stayed up, but actions such as pressing one of the control buttons caused the unit to lean and sway.

It also made a terrible noise when I turned it on.  It sounded like there was a piece of material contacting the blades which was constantly being rubbed.  Like sticking a card in bike spokes.  It went away after I power cycled the unit a few times.

Finally, the fan I received would rotate about 45 degrees to the left past center, but then come back to the left and only a few degrees past center.  I made certain that I had the unit properly aligned on the base - there is text on the bottom to assist in this.  Nevertheless, and despite the biased rotation, the complete sweep of only 60 degrees or so was way too small to spread air across a room; it hardly swept past a chair a few feet away.

Received 2 units in poor packaging. Box was not damaged,but upon taking both units  out, the side of one unit was bashed in, the fins were crooked on both units and I had to straighten them by hand, which by the way is not hard to do as the material very flimsy.. The caster plate attaches to the unit with butterfly nuts. One nut did not even have treads  on it from the manufacturer. I had to do what I could to make it work. After plugging one unit for 5 minutes, it tripped a 20 amp breaker. Had to go down on the heat setting,which affects the output and efficiency. The other unit has been on the whole night close to max in the office and this morning it was awfully cold in there.
Highly overrated by others. I would not buy one, especially for the money. Get a radiant heater with a fan. This just doesn't do the job.

Terrible performance at any price. I expect almost nothing at this price and got what I paid for. Don't do it.

Ordered two of these units for large automotive storage facility with over 3K cars and trucks. Fully charged and tested use. Both units operated only 5 to 10% of the time. Measured voltage at clamps and they had ZERO output. Suspect faulty internal protection design. Returned both units as defective.

Nothing but problems.  System operates sluggishly during basic task.

I rarely complain about products when they malfunction or don't live up to performance expectation. This product completely failed within a month of purchase!!I wish there had been a product review from another buyer. Battery installed well, and greatly improved my computer performance when initially installed. I had normal use, and turned off when not in use. This battery failed without normal "low battery" indicator signal. Poor product. Don't buy.(If company that sold this battery to me wants to compensate me or send me a better replacement...feel free mto contact me.)

Useless right out of the box.  A well known and documented issue: "pick motor stalled" (see HP's own forums) prevented initial setup as the machine was unable to pull even the first sheet of paper from either tray.  Spent over an hour performing various exercises per HP tech support which concluded with the tech admitting that this problem was all too common.  Her advice was to package this one up, send it back and don't even bother with another of the same model but suggested the 6700 instead.

There was a time when "HP" represented the utmost in quality and reliability, but that hasn't been the case for quite some time.  This is the final experience I intend to have voluntarily with any HP product.

Cheap materials, shoddy manufacturing, and unreliable. Please look for something else.

What a piece of crap! Poorly designed on/off button. The designers of this product should be canned. Returned it within days. I had to unplug the power cord and re-plug to turn it on. Took up to much space as well. Avoid this paper-weight.

Very poor quality control or design issues in the hardware.  Kindles have suffered with failing screens in the past (we've gone through 3 with this problem).  This time though mine failed the second time I turned it on.  Not acceptable.  Avoid until they fix this quality issue.

Poor quality construction.  Poor battery life.  Poor audio.  Non-resilient, low-fidelity bluetooth connection.  My advice for you is to spend a few more dollars and get a bluetooth receiver that will cause you a lot less aggravation and actually works for more than 2 or 3 weeks.  My device lasted about 3 weeks before it refused to power on.  Has been dead ever since despite trying to recharge from multiple 12v and 112v outlets and multiple charging cables.  During the timeframe that the device actually did work, the sound quality was erratic and inconsistent.  Whenever the sound would begin to fade or become weak and broken, I would stop the vehicle, connect to an available Bluetooth external speaker and sound quality was fine.  I would continue down the road 3-5 miles and, on he external speaker sound quality remained good.  Stopped the vehicle again and reconnected the iClever, and sound quality was crap again. Wrote the company about the issues and they, of course, assured me that their had a rigorous quality control program in place and that this must be one of the devices that got through in error.  Promised to replace the device but then, one week later, the device is now out of stock and they will issue a refund instead.  Guess how much of that refund I've seen?  You guessed it, zip-point-squat.  So, again, please, please, save yourself some time, money and aggravation and just purchase a bluetooth receiver from some other company that has a quality control program and an accounts payable department that actually work.

Terrible quality control as the other reviews have indicated. Don't waste your money.

I got the device and wanted to check it out. I plugged in an LED desk light. I checked out the buttons and found out that the desk lamp only used 4 watts. After about 30 seconds of pushing the buttons, the display lost 25% of the display. The display has four lines and the second one from the top just stopped working. Due to the nature of the display, with 25% of the display not working, it would be difficult if not impossible to read the numbers displayed, rendering the entire device unusable. Obviously, very shoddy quality control in the manufacturing process. All effort in the design and manufacturing of this device is obviously geared towards making it cheaper to produce with little to no effort expended to make the device robust and reliable. That is probably why Amazon quit offering the product themselves, too many returns from dissatisfied customers. I will be buying a more expensive but higher quality meter, since my time is worth a lot to me and I don't want to waste it ordering and returning shoddy goods.
