I have no idea how to get this thing open to install batteries. Can anyone help?

Yes - there is a little button on the bottom with a battery symbol. You have to press that down with one hand while you stick your fingernail under the end of the little cover that says "Logitech" closest to the battery button. It lifts up and pops off, like the trunk of a car. So non-intuitive not to mention awkward. Oh, and make sure you actually slide the other button to the "on" position or else it won't work, even if you get the batteries in correctly. Hope this helps!

Push the tab on the back and the front bottom will pop off. Insert battery and replace the cover.

There's a button on the bottom at the back of the mouse, push it and the top pops open. In it you'll find the USB plug and a space to put a battery. To close just pop the the plastic piece back into place.

It's such a great mouse but they did design the battery compartment like a hidden passageway and yet so simple to open once you know the secret. On the bottom there is a square button in the center beneath the on/off switch. Push that and the battery compartment on top of the device opens. I hope this helps.

The button is on the bottom. Can'T miss it!(It's darker and a different material than the rest of the mouse. The bottom of the top I will open

There is a little square button on the underside on the bottom, just press hard and the panel under the logitech logo will pop open. This will reveal the battery compartment and also a spot to keep the dongle when you're not using it or when traveling with your mouse.

Press down on end of clip and lift it up off of the battery compartment. This exposes the push opening in the middle of the battery compartment. Simply push that to open the compartment. RT

Press the battery sliding cover in a bit first before trying to slide it down. This makes is open much easier.

Are you talking about where to put the batteries? If so, you don't open the back. Open the faceplate and inside you will see a white cover. It has 2 big screw looking things that are latches. Turn them with a coin or wide screw driver. When they are horizontal, lift the plate from the flange between the 2 latches.

You need to pinch opposite sides of the battery flap with one hand and then release the top of the flap with your other hand. If you look at the flap on the back of the battery, you can see the hinges on the bottom of the flap which will help you see which side to release.

There are two screws on either side of the on/off switch. Unscrew them and a small battery drawer will come out.

I also have trouble getting the battery cover open. It works best if you pull up at the notch on top with you finger nail while pushing up on the cover.

This is very simple to open. You twist open where the arrows are for your batteries and then the battery holder just pulls out of the little holes that you line up. Just pull up, it comes right off! Just hold the bottom and pull gently on the black part.

Think everyone has this problem. Below the display is a small button like protrusion, push in on that and, volia, the battery door opens on the other side. The plus side of the battery goes down in the holder. You'll love this guage, it works great.

It's easy Mate. You carefully unscrew the base. Two of the AA's batteries insert one way..the third the other way. + \ -. The screwcap has two springs..and i tried using that as a guide for a while before I realized, there are two notches in the tailcap...one slightly larger than other...that only allow you to mount the batteries perfectly.

It's easy, Judy, but just a bit counter-intuitive. The Battery button releases the entire top of the mouse. It opens up like a clamshell to reveal the batteries. If you are like me, you are trying to open what appears to be a panel on the bottom of the mouse. It took me awhile to figure it out! Hope this helps.

Flip the light compartment up, and under that is a silver plate. At that point you should be able to see the locking hinges that hold the plate in place. The batteries are under that plate. Hope that this answer will help you.

There should be just 1 screw on the tab for the battery box, push the tab towards the middle and it should pop open.

The top of the device has a small indention. You can use the metal (visor attatchment) to open. It takes a bit of pressure but it's not bad. The battery is inside (CR2032) 3 volt. Good Luck.

Can't help. I returned it because I couldn't even figure out how to open the battery compartment!

I haven't tried opening this device. Behind the door on the side, i assume there are some screws behind the label. I don't know if the batteries will be standard or something dedicated...

I couldn't figure it out either. The instruction sheet is hidden between the paperboard insert in the packaging. The gridded panel on the underside slides over and comes off revealing the battery covers.
