Poor engineering, designed to fail.

This item and all others of this style produced by KES are a product very bad engineering and poor quality. Their valve system is terrible: The first one I had, the plastic button broke off. The second, water began leaking our of the valve piece after 1 month of use, flooding the bathroom floor and destroying all my base boards. Their customer service was good, they promptly sent a replacement over. Literally a week later, the valve on the replacement unit crapped out entirely and we now turn the spray on and off using the water shut off valve at the base of the hose. Avoid at all costs.

Purchased this Coby for my daughter, for her occasional use. She's generally careful and considerate of contemporary electronics, per my teachings, but this unit beats all others hands down - in the poorly designed category.

Three weeks of light use, and the headphone jack popped loose of the circuit board. In fact, the board itself failed  - delaminated at the points where the headphone jack was (briefly) attached. The headphone jack was secured to the circuit board with glue, and the electrical connection was made through the board with hair-sized wire! This is truly a feat of modern consumer-ripoff engineering  -  exactingly designed to fail after very little use.

Bottom line: if you forget you have it, and leave it in a drawer somewhere, it should last a while. But if you plan on using it, just sing yourself a song, while you put that twenty dollar bill back in your pocket.  Save your money and buy something that isn't just a waste of natural resources.

The product did not performed even under low expectations. The connector to the water feed is made of very weak plastic and the joining to the inner tube and cover fabric poorly design. At very little pressure it came apart. Connectors most be made of metal.

Did not work; did not stay on.
Poor design of mechanism.

VERY DISAPPOINTED in Weber.  While the base, center section, lid and grates are very well designed and well made, the access Door and access Door Assembly are cheap, flimsy, poorly designed, poorly engineered and poorly operating.  The latch assembly pulls out of the handle and doesn't allow the latch to rotate to seal with the body of the Center Section.  Today as I was preparing a brisket I put it on, and went to close the door and the whole door latch and handle fell off.  With a fire blazing and smoking from the sudden input of air, I had to spend over an hour to try and get the stupid latch back into the handle an hold closed.  There is a threaded insert that fits into a cylindrical  shaft in the handle which doesn't hold, and can't be tightened.  Because of this poor fit and design, the door doesn't seal tightly against the Center Section, and a large amount of smoke and heat escape out the top of the door.  POOR engineering and design.  NOT what you'd expect of a Weber.

DON'T buy this cooker/smoker.

The use of UV to prevent mold growth is great but the motor assembly is poorly designed, noisy, creates too much friction between the corkscrew and the tube (which results in the motor burning out) and the entire assembly is supposed to magically seal into the seat to hold water to allow it to flow out the channel.  I got it to work once but when it came time to clean it and replace the carbon filter I realized that the motor was nearly dead - burned out with corroded connections.
Like I said - good concept - poor execution.

This is a good idea but poorly engineered.
The good news: the light is bright and can be used in continuous or strobe mode for visibility. It fits well on running  and other relatively soft sided shoes and stays put. However if you want to use this for biking and have hard leather shoes with hard soles, as they say in a jersey, faggetaboutit.  My light lasted for one ride on my Specialized cycling shoes before falling off somewhere on a country road -- I only hope the squirrels and bunnies enjoyed the light until the batteries burned out.

And the battery situation is why I've given this only 1 star. First of all, it uses button batteries so they don't last that long in the first place. But the situation is made infinitely worse due to two big flaws. The first is mainly annoying: the switch is placed so that it's easily turned on accidentally if you carry the light in a gym bag, purse or other squishy container. The second is unforgivable:  in order to replace the batteries, you have to remove EIGHT microscrews -- and you'd better have a very teeny Phillips head screwdriver available and extremely dexterous fingers. Unbelievably, they make SEVEN of the screws identical and the eighth slightly longer, so you have to carefully examine the device to determine which hole the odd man out is supposed to fit into -- IF you happen to notice the difference before stripping on of the shorter screw holes. Finally, you'd better have another person handy since you really want three hands to accomplish all this. To replace batteries on a running light????  Come on!

Poor quality, poor engineering and design.
Cat does play with it if it will stay together long enough.

Parts don't fit together properly, the tabs that hold the pieces together are too small and break easy.  The plastic is very poor.

While the wood in this shelf unit is fine, the engineering and design are very poor.  The small "nibs" that were intended to hold the top on and, thus, secure he entire unit together were totally non-functional.  I had to design four screw-on tabs to hold the top onto the unit.  The whole bookcase itself is unstable and "wobbly."

Poor design.
1. Flimsy construction, corrugated plastic frame.  Was broken before its first trip (see hereunder)
2. Unstable. The front wheels are positioned too far back; so when loaded, the front protrudes too far in front of the wheel and the case is not stable. I doubt it would stand with the extension opened and the case full.
3. No side handle, only one on the top.  A case of this size needs a side handle from lifting it or removing from a trunk.

It did not make it to the airport. I had just packed it for its first trip.  I needed to lift it and was looking for a handle I expected to be the side. I leaned a little on the suitcase while looking and heard a "pop".  The inside corrugated plastic bottom had cracked and now the base of one of the wheels was bending, as a result, the case started tipping over when loaded.

The  design requires strict manufacturing tolerances that simply aren't met. Most of the traps will not work.

I'm amazed that a factory allowed such a piece of junk to be sold to its customers, and then that customer went on to sell it to me.  This is a very simple device, yet it fails.  The handle doesn't attach to the bottle properly, meaning that I need to use this with two hands - one to squeeze the handle and one to hold the bottle separately.  At first I thought I might have done something to cause the failure, but the threading isn't even close.  This is faulty by design.  My worst purchase on Amazon in my many years of happy purchasing.

Poor construction. I would not recommend this product to anyone.

Poor construction and/or quality control will cause this timer to fail, most likely sooner rather than later. I have been through several of these and similar units and in all of them the timer mechanisms have failed. Several were defective and did not keep proper time right out of the box. Others began losing hours every day after a few months. The one that lasted the longest worked for about a year before it failed. Look for another product.

We needed to replace the ground fault receptacle in our upstairs bathroom.  I have a fair amount of experience in basic electrical wiring.  The 51960 suffers from a major design error in the line and load screws.  The nut that receives the screw is not designed to completely release the screw.  You, the user or installer, are supposed to manage bending your copper wire around the screw while it only gives you half a centimeter of room to work with.  The logical idea is to completely remove the screw, move the wire in place, and re-insert the screw.  This is where the major design flaw sets in.  Being that the screws were not supposed to be completely removed, the nut loosely floats around in the main receptacle.  I tried for over half an hour trying to re-attach the screw to the nut.  I tried without the copper wire.  I let my wife try with her tiny hands.  No success, not even close.  If you remove the screw completely from the main part, you item is now broken and basically unfixable unless you want to completely disassemble the receptacle.

To GE - a child could have designed a better screw system for you ground fault receptacle.  Shame on Lowe's for selling this POOR product.  I would not take these ground fault receptacles if they were giving them away.  You will pay greatly with your personal time during installation.

This is s*** for the money. These companies need to get better engineers

The idea to have a tool that promise what this is interesting, but the design and material must be revised. It is made from a really fragile alloy and will not whistand any moderately tight bolt. The screwdriver part cracked when attempting to use it on the tinny screws of a desk phone.  The bottle opener is too dificult to use succesfully.
