Great value. May be a bit fragile or inconsistent in durability.

I really like the JieJia goggles from China. The fit and seal are great--much better than some goggles that I spent a lot more money on. This is my fourth pair. My only complaint has to do with the durability of one of the goggles--the bridge (between the lenses) broke when I dropped them from about waist height. Yeah, I dropped them so it was my fault but I really did not expect them to break so easily, and they were brand new at the time.

This clamp appears to be as described by the seller and a good value. It is well designed and while I have seen stronger metal parts, screws and adjusting hardware in particular, they also command a little higher price. I think it will be fine for occasional to moderate use however daily use might result in failure. With that said, if would be easy to upgrade a few of these parts, spigot and knobs, to make it a little stronger.

Bottom line is I would buy again and probably will order another one or two based on the cost/value.

Good value replacement, but these break after a year or two of regular use when one kink happens in tubing.

I needed to replace these for a couple of my sliding closet doors. They are not incredibly sturdy, but are a great value for the price. They guide the doors well, but look like they would break if the doors were leaned on heavily. I found them worth the price -- if one breaks I now have several spares.

Great price , but it did have some quality issues  (some lose threads)

The fastener rivets worked well but they were a bit loose. I think they were made to fit "most" vehicles as opposed to perfectly fitting a specific model. As such they tend to be either a little loose or sometimes too snug. Other than that, for the price it was a great value. This is the second time I buy those and I end up handing half of them to friends and family as I only need a couple here and there.

Great value for a good quality product.  That doesn't happen often.

These were a great deal, but one out of five now has a connector that won't make proper contact (after a month of occasional use, maybe 10 times).  Other four are great though and I'm still happy enough with the deal overall.

great value. Used all of them on some cart I needed to built.

Buyers be aware, these are not heavy duty casters. Please don't load them with more then 50 lbs per caster and complain that they will break. They are not made for this load.
This said, yes, they will break easily when you put a lot of load of them. The rubber wheel will sheer of and shatter in multiple parts. Happened to me too. As I said, great value, not heavy duty.

Feels like most of the moving parts will break without much use, but until they do... 4 stars at this price.

Good value.  Not perfect construction, as one of the plastic flaps on top arrived loose, so you can't use that compartment for screws, etc, but gets the job done for a low price.

Really good set of cables. All five of them worked fine on arrival which is great considering others have not been so fortunate. Well I have exactly five siblings who have used these for the past several months. None reported slow charging times, some even said theirs improved. Now for the durability. While they have a nice design they are quite delicate. If you move the cable too much it will eventually go out. So far i have had two partially go out. you have to move them in a certain position to work. For $5 however, its a pretty good deal.

Nice design, Bright and Great for the price, but would probably break if accidentally dropped on a hard surface.

Great value. I'm not nice to this bag. I pack it full to the point the zippers seem like they might bust open but they always seems to hold up. The only HUGE flaw I can point out in my case are the "D rings" that support the shoulder strap. Over about a months time they began to ware out and open up causing my strap to fail and my laptop hit the ground. Shortly after the other side did the same. I recommend replacing these or modifying them to make sure this doesn't happen to your computer.

You can't beat the price, so I probably shouldn't complain... But: the metal is somewhat flexible. They work great and look great, and I think they are as safe as any other one, but they are probably not very durable.

Important: if the sill that you screw the second part on is not very deep, you will likely have an issue opening the window. I had to reshape them all a bit.

For the price I really cant complain all thats much, its a great value. However, I only received 109, two were damaged, and I got one duplicate. Another thing I would like to point out, in my one picture you can see how they are different lengths. These were supposed to all be 5/8 if I read it correctly. Some are 5/8, but some are smaller in length. So just be aware of that before ordering. The two damages I had, one having a striped threading in the ball and the other had a hole going straight through the ball. But like I said, for the price I paid, I would say it was worth it.

Very good value.  Might not last as long (forever) as Le Creuset, but for the price, you can afford to replace it.
