PROS:* Affordable and well built* Plastic construction seems to be durable, yet flexible* Thick enough that it shouldn't easily break, but my all my screws I had fit ok.* Had all the holes where I needed them which is always a plus* Comes with four mounting screws to mount the adapter to your case. (You provide the screws needed to mount your drive or other device to the adapter. These mounting screws typically come with your drive, front panel hub, card reader or whatever else you're installing)* 2 Year Warranty* The black color matches my Anker USB 3.0 hub and case perfectly.CONS:There really isn't much I'm displeased with, but here are a few things worth mentioning.- There is a slight gap around the Anker USB hub I installed in this. Not major, but if you're expecting a very tight "force it in" fit you might not get it with all devices. I'm worried it might let some dust in but time will tell.- I've read some people have issues with the plastic being too thick for their drive mounting screws. I mention it here but had no issues myself. If there is any issues I suppose you could always get longer screws, remove any washers, or countersink holes slightly if you need to make short screws work.- This is plastic so if you force things I'm sure it will break.- The mounting screws to mount the drive adapter to the case are those sort of "self-tapping" screws or sheet metal screws that chew into the plastic to make their own threads and secure the plastic. In my experience these work fine a few times, but the plastic typically won't hold up if you constantly remove and reinstall them. If you're one of those people that constantly changes things around and builds new computers from existing parts it's something to be aware of. I'm sure you'd have to remove and reinstall this adapter many many times before you chewed the plastic up so much the screws wouldn't hold.Product Dimensions:8Height 1.1 in [28.6 mm]Length 5.7 in [146 mm]Width 5.3 in [133.4 mm]..MY EXPERIENCE:I purchased this to install a USB 3.0 front panel hub to add USB 3.0 ports to the front of a computer. It worked nearly perfectly for this use. The USB 3.0 front panel was being installed in an unused 5.25" optical drive expansion bay on a retail HP computer. I needed a 3.5" to 5.25" drive adapter that looked great but had a low profile face and didn't stick out very far. This was necessary to allow the USB ports to be tucked back behind a drive bay door cover to maintain a stock appearance while still providing access to the ports.This mounting adapter fit fine in the stock OEM case's 5.25" drive bay and mounted without issues. The adapter comes with 4 screws to mount it to your case's drive bay. Since this was a stock OEM HP case you can't easily remove one side and so I could only use two of the mounting screws but that's all that is necessary to keep things from sliding around.The ANKER USB 3.0 front panel hub fit with some room to spare. The USB front panel hub doesn't completely fill the hole for the 3.5 inch drive so there is a slight gap around the hub sides and top between the USB hub and the adapter. It's not a huge gap, it looks somewhere between 1/32" to 1/16", but it's enough to notice light and see through when out of the case. When everything is installed in the case I don't really notice the cap at all. This doesn't bother me. Since this is a "one size fits most/all" adapter you can't expect a light tight perfect fit. I could have evened up the gap between the bottom and top by using some washers as spacers on the bottom mounting points. I also could have used some sort of black trim on the inside to really seal this off but I didn't take the time. I'm a little worried about how much dust the gap would let in but this install hides behind an HP optical drive bay expansion bay door cover. The gap doesn't bother me much but I thought I'd mention it. I'd much rather have a little extra room and NOT need to get out files, grinders or sandpaper to make things fit so I won't complain.I didn't have any issues with mounting things up. Screws were just long enough to safely secure everything. It doesn't take much. We're not bolting down jet engines here ;)I'm uploading plenty of images but there really isn't much more to say. Based on the price, fit and final appearance I can definitely recommend this adapter.
