The size, position of the hooks, and overall composition of this "unit" make for an awkward item that really is not useful for too much of anything.  I've tried using it for coins in the console, but due to the swaying nature of the small loop on the bag itself, it doesn't even hold coins.  Not worth a dime.  It's not ideal for my iPhone 6, my sunglasses are usually on my head or in their case, which, while cased the Oakleys are too large for this caddy too.  Doesn't work for me.

This is a nice enough caddy but why on earth these caddys are not made with something that actually HOLDS them securely between your mattress & boxsprings is a real mystery because it wouldn't be that hard to do & customers would be so much happier.  I ordered this piece knowing that I would probably have to make some modification - I like the wide design and it does have nice size pockets etc for holding things.  I just pinned it in three places to the side of my bedskirt and also pinned the two tabs to my bedskirt under the mattress.  We will see if this works well because I just received it.

I purchased this shower caddy for the stainless steel feature because I was sick of caddies that rusted...  This one is very nice and will not rust, or at least that is what the selling feature is, but bottles of shampoo, conditioner, etc. will not stand up in it???  The slats on the caddy are going the wrong way I think and it causes the bottles to fall out...  Also my husband had to add a piece of rubber so that it wouldn't slip of of the shower head...  I'm hoping that I can figure out a way to keep the bottles in place...

Sent my daughter to college with this seemingly great caddy. Broke within 60 days and unable to return??? Certainly cannot afford to purchase this 16 times over her college days. Hoping owner sees this and will replace or refund.

I have never bought a product from Amazon that was as unsatisfactory as this one. First, the item is basically junk, poorly engineered/designed and almost impossible to install even by the talented handyman who did the installation.  He had to jury rig the caddy with parts from the caddy (different brand) that was being replaced. Further, these issues suggest that the product life will also be disappointing.

If this Zenna caddy hadn't been installed I would have returned it for a full refund. I am disappointed that Amazon would carry such an inferior product.

You have to flex the caddy in order to get the drive in it.  The inner posts were almost impossible to seat correctly, and once I had the drive in place, the caddy was still flexed.  I ended up removing the posts on one side (screw driver used as small chisel, and a hammer), seating the drive over the posts on the other side first, and then it returned to a nearly flat configuration. At least it stood up to all the bending!

Had to change my review.  Took my bike out for just the 2nd time with this bottle holder, all just as before.  Bottle full, same road down to the railroad access trail, over dirt and gravel and rock, only this time the holder broke!  The bottom tang that keeps the bottle from sliding down cracked right at the mount!  So, unless you're carrying a half-full bottle...on smooth paved roads...going no more than 15 mph, it will probably work fine.  But for those of us who actually RIDE our bikes and take them off-road and get them dirty...this is just not for you.  Fortunately, since this took so long to get shipped to me (over 2 weeks), I had already ordered an all-aluminum holder which I shall install tonight.  And I'm sure I shall get YEARS of service out of it...for virtually the same price!  My suggestion: shop elsewhere.

This item is not what I expected it to be.
Firstly, the handle is not as long as the picture makes it seem. The handle is only a few inches long, which is the same length as a Caddy with two handles. So there is no benefit of the one long handle. Secondly, after the first use it has already started to break. The thread holding the fabric to the mesh is undoing itself. I've only been using it for a week, and the thread separating two of the pockets has completely undone itself and it is now one large pocket. Also, the handle's thread is coming undone as well. Thirdly, this Caddy has no defined shape. So as you carry it, your items will move around and the Caddy will take any shape. This might not seem like a big deal, but for a college student like me that doesn't have much room to take a shower, having a shower Caddy take up half of the limited space isn't helpful.
I did not like this product in the slightest.
I hope this was helpful.

Its a nice caddy but rusts terribly. This is the second one I've owned. The first one rusted really badly but I thought maybe they resolved the the problem. I was wrong. I should have read the reviews. Oh well, I guess I'll have to find something else.

I bought this last week and installed it, intending to test a secondary hard drive in it.  I ended up not needing it for that, so the caddy just sat empty and without a purpose inside my T420 laptop for a few days.  BIG MISTAKE.  Last night while I was typing with the laptop in my lap, I shifted my weight and the laptop violently shut off.  It would not turn back on, even plugged in.

I shook the laptop a little and heard something rattling around loose inside.  Once I took the laptop apart to investigate, a single screw fell out from inside that had just been flying around loose all over the motherboard, shorting out electrical components everywhere willy-nilly.  This was one of the screws that came with THIS caddy for holding its drive in place.  It had easily backed itself all the way back up its many threads, where it was dumped out directly onto my laptop's main board.

***
EDIT: I almost forgot the best part:  At this point I realized what the screw came from and tried to slide this hard drive caddy out.  It was STUCK in the laptop.  That's right, even with the one screw out of the way there must have been ANOTHER one loose enough to make the caddy completely un-remove-able.  No amount of actuating the switches and bumping it at different angles could get it loose.  Because of this I had the joy of taking the laptop completely apart all the way down to just the motherboard on its frame, including the CPU fan assembly (which meant having to go out and buy thermal paste to re-install), and pull the bottom cover off the laptop and to free up this shoddy caddy that was so firmly gripping the insides of the UltraBay slot.
***

The thought of a cheaply-made hard-drive caddy destroying not just itself, but my whole computer, is completely unexpected and unacceptable.  The fact that I didn't even need it after all (since I fixed my hard drive some other way) making it a waste for me to have even bought this caddy to begin with... it makes me want to throw up, because I didn't even need to keep it, but did anyway just to hang on to it.

In a stroke of luck, taking the whole laptop apart and finding and removing the loose screws that came from the caddy brought my computer back to life, but right up until then the whole laptop was a brick.  Most circuit failures that cause apparent symptoms, or that involve a loose screw shorting lots of things out, would typically be permanent and unrecoverable (burnt SMD components, melted traces, other damage), and not just reverse themselves after a while.  I am VERY lucky to still have a laptop.

This is a fatal and stupid design flaw, considering that other UltraBay caddies on the market that I've bought do not even rely on screws at all to hold the hard-drive still, instead bothering to include their own latching mechanisms.  The screws in this one spin and flop around loosely in their threads and there are no safety measures taken to hold them in captive.  They are designed to fall out not towards the caddy on the inside, but outside of it and onto your main board.  This unnecessary design difference compared to other UltraBay caddies just to save a few cents is pitiful.

NEVER BUY THIS PRODUCT.

IF YOU ALREADY DID, THROW IT AWAY, ACCEPT THE SMALL LOSS WHILE YOU STILL CAN, AND BUY A SAFER ONE INSTEAD.

This looks like a winner but when it arrives it has four screws and a caddy, no documentation or instructions for installing. There are no holes for the screws to go into and this caddy would have to flop around inside the macbook pro.

I decided to give it a try in my 15" Early 2011 MacBook Pro (unibody) and found that it was barely adequate. Also the SSD just hangs off the physical connector and has no support. Other issues:

1) You will need to pull off a strip of plastic from the caddy so that the caddy will fit and the radio component can go back into place. This actually looks like it is designed to be removed depending on the machine it's going in because it has a couple of lugs. When I was prying it off one of the lugs broke of course and I couldn't get it out. I left it there.
2) To help keep the SSD in place while installing I had to wedge in some cardboard. This helps to take the strain off the SSD while you're trying to get the caddy in (Pictures uploaded).

Not a good choice IMHO . Shell out the extra bucks and get the OptiBay for $99 and then you'll have the enclosure for the optical drive also. I'll stick with it now because I don't want to go through all this again but I would not advise anyone to use it.

I installed 8GB memory, a 500GB 7200 RPM WD drive (Scorpio) and the SSD and put the original Hitachi 750 GB drive in an external enclosure to use as a time machine drive. The enclosure was $20 from OWC (USB3) and a set of screwdrivers was $5 from OWC. The screwdrivers were useful because they were magnetized and the screws are in some tight spots.

I put the SSD in the optical bay because the hard drive temp and motion sensors are not present in the optical bay.

The little caddy is a nice size and seems sturdy. However, it showed up without the drawer that goes in the middle... I read the Q&A post about this and wasn't even worried about not getting the drawer! What the heck. Now it looks like a weird empty space things fall out of.

This caddy looked great when it arrived; however, it is extremely hard to get the tension rod set up correctly. I may have gotten a faulty one, I don't know but I can't seem to set it so that it will stay up for extended periods of time. It doesn't have a spring in it. I really can't explain how it works but it's not your normal tension rod set-up. I can't count how many times this thing has come crashing down in the middle of the night breaking some of my bath items. In addition, I've already had to repaint it because it has started rusting. Overall, I expected more out of something this expensive. I got more use out of a $15 caddy from Wal-Mart and it actually had a tension system that kept it in place. Avoid this if you want something that works. There are probably other things out there that are cheaper (like Wal-Mart) that work better.

UPDATE: Amazon is working to refund me for this. Amazon is awesome. This product is not.

It looks nice, and runs fine, but no better then our 10 year old dishwasher it replaced.  The pullout rack is poorly designed. When you pull it out, you have to be very careful or it will come out of the track. The track is not deep enough, or the wheels are to loose, or a combination of the above. It is really annoying.  The racks are made with very thin metal, bend easy, and will probably not last as long as previous models.  I wish I would have found something better.

Got this for my 99 caddy. Will let you know later how it works. Although anything should be an improvement.

The caddy is fine.  However it's sitting on the floor of my bathroom closet because the superior suction cups... well, they suck.  I have non-porous tile, that is always cleaned weekly and was prepped as directed before installation.  Perhaps I got a bad run if the double sided tape.  However, the replacements to try and make use of this caddy again are $5 each... for a plastic disc with double sided tape.  I don't have to tell you about all the great things you can get on amazon for $5.  These should be a couple bucks for a pair.  So, now I'm going to just find a caddy to mount permanently.

I was really hoping this Tub and shower basket would work.  I keep a bottle of shampoo, a bar of soap, and a razor on the narrow ledge of our tub.  These items are in constant competition with the many and various bottles of lotions, shampoos, and creams my wife tries to also keep handy by the tub/shower.  This looked like the perfect answer to increase storage area without hanging something on the shower head.  Over the past 8 days the same suction cup on one end of the basket has let go 3 times.  After the first failure I cleaned the tiles with Windex and wiped off the suction cups. 3 days later the same suction cup failed again.  I repeated the cleaning process and attached the basket again.  This afternoon I heard the tell tale crash from the bathroom again.  I have now installed the basket at the end of the tub, so the weight is supported by the tub spout, in hopes that it will work better.  This is not the ideal location for me however, and if it does stay on the wall this time, I will still be settling for a second best location.  I have tried 4 or 5 other items like this over the years and am coming to the conclusion that none will work for very long.  I considered super glue but my wife was quick to veto that idea ( and she is probably right )
