Inexpensive, Works Well, May not last Forever

The housing (body) is metal as well as the plunger shaft.
the "plastic" nozzle retainer is also metal. So, the nozzle,
release button, thumb depression button as well as the
inner suction damn is plastic. The o-ring appears to be
rubber.

I think this device has enough metal with plastic in the right
places to hold up and work well over time, which it does
right now.

I received it scratched a bit, the packaging could be a little
better but that may increase its selling price so I'm ok with
it not looking brand-brand new.

My one real (minor) complaint is that the threads for the nozzle
retainer which holds the nozzle in place are very fine and not
machined to the highest standard. In time I can see the body
and retainer grinding the threads of each other down and in time
failing. I'm not complaining because this is an inexpensive
tool, just be aware your not getting a Mercedes at a VW price.

All in all, I'm happy with my purchase and I think you would be to.

Easy to install, but not as long of use as I would like.

Works well - not very robust, but a good value at such a low price.

Works for exactly what you want it to.  But, the metal prongs break off VERY easily if you're not careful.  I think if you limit yourself to taking the battery off from top to bottom, reducing pull on the prongs, you'll get longer life.  I have one that's lasted for only a couple weeks but I've had others last for months.  Take the risk at this price, I say.

Cheap plastic, but low price and works so far

Good for what it is - an inexpensive, mildly powerful amp. But let's be honest, you're not buyig this for state of the art, high quality sound and longevity.
Believe it or not, it lasted 4 years of college fraternity parties for me, and then one channel crapped out after I brought it home.
I used it to power two 400W rms peavey speakers and it worked pretty well with a pre amp mixer.
Overall, it's certainly durable (had been dropped numerous times, beer spilt on it etc), but unless you really take care of it, eventually something will go wrong with it.

Worked great.  But 3 or 4 years later, it's not snug in the usb port on my MAC, and I'm always getting a error message that my printer is not connected.  Sometimes I can slide something underneath it to keep it level and it'll work.  It's hit or miss.  I don't know what the life of this cable should be.  So cheap, I'll probably just buy another.

This is very easy to use and works well until you've had it for a few months and the battery stops holding a charge.  We have used it very infrequently, keeping it on the charger all of the time.  However, after less than two years it only holds enough charge to maybe put in one screw.

There are certainly fancier and more expensive 14500 chargers around, but this one is simple and functional.

Like most inexpensive chargers it appears to be charging two batteries in parallel, which seems rather dubious, but it also seems to work. Of course I never buy anything but the "chipped" (protected) Li-Ion batteries, so YMMV.

The unit is pretty self-explanatory. When a battery is charging, the LED on the charger is red. When the battery is charged, the LED is green.

The case is inexpensive fairly brittle plastic, and isn't going to stand up to major abuse. The batteries are not held very securely in the charger, but securely enough if your house doesn't move much.

So for most purposes, this device seems to be all it needs to be.

Works well but doesn't seem to be very solid and I wonder how long it will last?

This Ac Adapter Charger Power Cord Supply is inexpensive and functions the way it is intended. After one year it started making a popping, crackling sound and smelled of burning plastic. I am not sure if it's an overall flaw or just one bad product. The reason for my re-purchase was related to cost and the fact that I more than likely would be replacing the laptop inside of another year.

This charger worked well when my other one went bad.  It was also very inexpensive.  However it has stopped working after 3 months.  Some other reviewers mention the loose connection to the adaptor and that is what has happened with mine.  Now it is not charging at all.  But I don't feel a huge loss because I didn't spend much money on it.  Thought I would take a chance, and I did, but now it no longer works.

Works as advertised, but after several uses it doesn't seem to charge as long.

Worked very well for a while, but the wires are beginning to pull apart from the plastic components. Still working, but it's on its way out. Still, definitely worth it for the price, if you are okay with a cheap alternative. A more expensive unit should last longer, but this one is perfect if you are on a budget.

Works well while it works...i've now had two die on me, but it took 1-2 years for it to suddenly stop functioning.

Okay for the price (it was quite a bit cheaper here when I bought it).  I needed an inexpensive tape dispenser and I'm overall fairly happy with this product.  It's a little on the flimsy side.  The spring-loaded metal part on the bottom that is supposed to hold the tape in place was too aggressive...the spring was very tight and strong.  I bypassed the spring and that made it a lot easier to use.

I've used this a lot every day for the past 8 months and it's still doing its job!

UPDATE 3/23/2016:  After around 15 months of fairly intense daily use, the dispenser finally bit the dust.  The culprit was the flat large side piece that all of the components attach to.  It is made out of plastic on this item instead of metal like some other dispensers, which obviously limits its durability.  However, I'm still overall satisfied with my purchase, largely due to the very low price I got this at, which was less than half the current going rate.  Considering the great price, and 15 months of service, I can't really fault it.  But, you can now find dispensers in the same price range that are made of metal and are bound to be more durable and a better value.

Simple to install, but probably will not stand the test of time and weather.
