3.5mm connector fits loosely, doesn't make good connection.

Case is a good quality. Works good. As stated in other reviews it is a tight fit and you have to push hard to get it to plug all the way in.

This works, but was frustrating as a previous review noted, the center just pops out of the back. I had to pull the plate, pull the single gang mounting bracket, and re-fish the wall to re-seat this connector into the keystone. Installation was tight as well, it took a lot of force to finally get it into place and I felt like it was going to snap during installation because it is so flimsy. I coupled this with "C2G / Cables to Go 40016 Velocity Right Angle Toslink Adapter" so that I could install the toslink and not have to worry about a cable break and it did the trick. In order to get this to work though, I had to put both connections into the keystone/wall plate, and then screw it to the wall. Certainly not a "plug-n-go" quality keystone.

It works. It works good. But it is a narrow fit. It must be place perfectly over the screen in order for it to cover the screen and it's frustrating. Once it's installed it works great but it's such a tight fit and is such a headache which is why I gave it three stars.

Ok, I'm not that experienced with this sort of thing, but I did manage to solder the headphone wires onto the terminals on this plug, and at that point the phones were working well. The problem arose when I tried to slide the cover over the assembly - it was way too bulky to fit! So I compressed it this way and that until i got it in there, but of course in doing so, the connection was pretty much ruined.

A bit cumbersome with the attached plug and a bit difficult to unplug your electronic items.  I really have to use some muscle just to pry loose anything I happen to plug in.

Seems to work.  Unfortunate that the capacity is less than the original battery.  My complaint is with the type of connector used here by B and N.  It doesn't attach very securely, and after installing this replacement I had a lot of trouble getting it to make a good connection (symptoms are that it won't turn on or that it starts acting possessed, clicking on things as if someone else is controlling it).

Anyway I put the connector firmly in place, but even when it seemed like it had locked in place, when I tested it out (and it didn't work) and I opened it back up I would find that it was barely on there.  Eventually I took some electrical tape and folded it over itself again and again to make a lump, then taped the lump over the connector.  That way once the back cover is put on it will apply pressure to the connector and keep it in place.  Some sort of removable glue would probably be good, so long as you could replace it again in the future.

To get the connector off, it's easiest to use a stiff wire or thin tool to pry gently under the wires right where they come of of the connector.  It takes very little force to take it off.  The biggest pain of this process is snaking the old connector and wire through the small passageway to the battery compartment, and then snaking the new connector and wire back through that tunnel when you put in the new battery.  Takes time and patience...

Won't fit in my car adapter far enough to get a connection for the USB ports

Using this with a new DSiXL, it fit so poorly that the charging indicator light stayed off unless the plug was held carefully to assure contact was made. It needs the kind of special attention I never want a connection cable to require,

Works but wish the side with ports was about 1/8in (3mm) thinner cause it is hard to get some devices plugged in

The power plug does not fit completely into socket. Returning this item

These work, but the contact is somewhat annoying and way too hard to get the batteries in. Sorta wish the plug wasn't integrated and was on a short cord as well, since this thing is fairly huge to plug in and covers any other sockets near it. But it does work the couple of times I have used it so far.

The product (AC Adaptor) met the power specifications, but the power plug that attaches to my laptop was not a snug fit.  A loose plug will likely cause power drops and/or potential shorting.  I asked the vendor to ship what I ordered and was told that what was shipped would work.  A disappointing experience.

works but you really have to play around with it to get it fit properly

I was hoping it would allow me to have USB OTG on my android phone and charge my phone at the same time, but alas, it didn't.  I knew this might be possible going in given OTG was meant to power external devices, leaving no pins open for charging the host device while it was powering the USB device.

I rated this 3 stars because both the female connectors were too tight fitting.  I found it difficult to plug other USB devices into them.  Unplugging was equally difficult.  Haven't broken anything, but it's a bit alarming how much force is needed.  I can hear an audible *THUNK* as I plug cables in when typically, I can just slide the usb plugs into each other with no *THUNK* sound.
