fuses fall apart, melt, burn. junk

do NOT trust these, very likely if left unnoticed they will start a fire as they don't "pop" but melt and keep working.

Zero stars for this product if I could give that rating.  I purchased two of these from another vendor to dehumidify a very large safe I have, and they work.  I live on the coast so lots of humidity.  Every few weeks I have to stick them in the electrical socket and 'renew' (dry out) the silica inside.

The way it works is the device plugs in and then heats up from the electricity being applied to it.  The thing can get quite hot.  Not so hot you ca't touch it, but pretty hot.  They plug in via a fold-out plug in the base of the device.  You are supposed to plug it into the wall and tension from the electrical plug holds this rather heavy device - sometimes just baaaarely - in the wall.  I am using fairly new electrical sockets to do this.  Older ones have worn to the point where they just fall out.

So, over the course of several months, these two devices stopped wanting to stay in the socket.  I had to prop them up somehow with a box or similar to keep them jammed into the socket.  Not happy with this setup, I decided to use a short 2-to-1 extension and attach them to a power strip, on a cement floor so - knowing they get hot - they won't set anything on fire.  I stood them end-up to match the position they would be in normally.  This worked fine for a couple of times, but one day they fell over.  The pictures you see are the aftermath.  The plastic was soft and flexible like taffy and you can see in the pics I have pulled them apart slightly.  I left them like this to cool and eventually when the plastic re-hardened they pulled apart just fine, but deformed as you can imagine.

These things get so hot they will melt their plastic casing in otherwise ordinary use if just one wrong thing happens.  No thanks!  Manufacturer has produced a product that is too easily rendered dangerous.

We moved to UK and the third time we used it  broke down. Fuse was not blown. The entire transformer got burned!

Shorted out and melted the casing rendering it useless. I got a warning while using it on my new iMac that it was drawing too much power and would shut down USB devices. Didn't think much until I pulled the adapter and noticed the entire corner of it was deformed as it had shorted out and heated the plastic to melting point. Luckily the computer shut down USB power or it may have continued to burn and eventually catch on fire. Will not buy again, it is cheap chinese made junk and I won't trust it with my SSDs or computers.

melt down....  Replace both male and female plugs.  Everything went together w/o a problem. Had a solid connection and it clicked when they plugged together.  An hour later I check recharge progress and this plug melted down and almost started a fire.  Avoid at all cost and don't trust.

Leaving one star because I can't leave zero. I have had to replace every one of the lights. I had 2 actually melt down and BURN. If I had left the lights on and left them unattended, it probably would have caught fire. If you value your stuff. DO NOT BUY THESE LIGHTS.

pretty horrible. i ordered three of these to hang up and the fuses in the wires blew every single time i plugged the strand in. (and it came with a replacement fuse). also - i went to hang up the lights and the plugs don't secure into the socket they're plugged into - the weight of the strand pulled the plug form the socket and the whole thing came crashing down and broke all over the patio. don't bother.

Ok, so I got these to use for my  license place lights on my 2012 mini cooper.  What junk and what a headache.  First 2 I tried to install, only 1 of the diodes on each bulb would light on either side (not due to polarization).  Second 2 lit properly and were installed.  On the first drive I took the left bulb shorted out and caught flame.  Damaged the bulb holder and the entire bulb housing.  Had to order both of these new as they were ruined.  I Wish I could upload pictures.  This cost me $34.17 and I've got to drive around with only 1/2 my license plate illuminated.  Product is clearly sub-standard and, quite frankly, unsafe.  Had the plastic housing not been relatively air-tight, the fire could have taken over the whole car.  If I could give less thank 1 star, I would.  Be warned and be careful.
p.s. 2nd load of rubbish that I send back from cutequeen.  Other were different LEDs that didn't work either. At least those didn't burn up anything...

Lasted a couple of months and melted. If you buy one make sure you have a circuit breaker.

These are crap- the wiring is such small gauge that my Imax Mini charger won't even detect that a battery is attached- gives an open port fault and won't charge. I tried to solder a bigger wire to it, and the metal melted out of the plastic holder- complete junk.

I bought two of these on ebay because ebay cost $11 each including a 30 amp fuse. It arrived quickly and I installed it quickly to reduce fuse holder space. However as soon as I installed the device and turned on the solar panel switch I found the fuse holder became extremely hot. I immediately shut off the solar panel and remove the fuse from the holder; the fuse is so hot I could not even hold it. After it cooled down, I used a DM and found the fuse has 5.6 ohms resistance. Imagine power is V x I  or I x R x I or I squared x R. If my solar panel is putting out 20 amps, it is 400 x 5.6 = 2240 watts., no wonder it is so hot instantly. I could not use this fuse. I have not try other fuses but DIY people beware. One should check the resistance of the fuses before install it on the system. It can easily burned the fuse holder and cause a fire !!!

I bought two of these to add to my SmartThings system.  They both burn through batteries pretty quickly, and one of them fell apart (The battery became disconnected from the circuit board).  My advice, don't waste your money on these, and if you do, make sure it stays in a protected space.  They are too fragile.

Do not waste your money on this. Burnt my fuses every time I plugged this into my car.

The connectors came apart and caused a fire on flammable material and I am on oxygen and could have killed me.

This fuse got so hot I burned my hand using a 36 lb trolling motor with it. I don't know why it didn't trip but I took it off. It may be a one time issue or a faulty breaker but I would probably avoid and get something of better quality.

This power supply fried and melted within 2 months. 3 of the 5 connector pins failed. The plastic on the end that houses the sloppy connections actually melted, allowing me to really see how it was constructed poorly. Last and certainly not least, the connector arcs on the Surface if you're not oh so careful, in fact, yesterday it happened and shut my Surface down, i had to call Microsoft to get it to boot again.

was so hot that it melted the bulb holder the standard bulb was better...do not buy this product
