the other answer is great - just wanted to add that there are many other devices you may want to connect to your computer via Bluetooth. speakers, a mouse and/or keyboard, a phone or tablet for wireless file transfer or sharing Internet between the devices, etc. Even some printers can be connected via Bluetooth.

You don't absolutely need it, but it is convenient it you ever need to work on your system; so I suggest you use it.

The only thing I can tell you is it is for connecting to a male quick disconnect Foster fitting. I figure the 1st reply was the best answer to your question.

Hmm im not too sure... but im not sure you would need it! I would look in to that before you buy this product if it really means that much to you.

It is for connecting two devices to one usb port, in and of itself it provides no power whatsoever, nor does it in anyway provide or enable whatever software is required to make devices work. Clear? It is excellent for connecting two non-powered items such as a key board and mouse. In addition there is no switching mechanism, thus its function is to make available two usb ports using only one on the computer.

I used it to unfreeze computer from a ransom ware situation. I don't know what it will do about your computers performance.

I never even looked, but it is probably unnecessary. It has a feature for allowing the internal mike to zoom in a speaker and that actually works.

Not sure. This was given to my grandson and I don't believe he has had a need.

It is used for mounting the suction to your dash if your dash doesn't allow normal suction. I use it and it works perfectly. I'm not concerned with the possibility of damaging my dash because of the material it is made of... you will have to make that call on your own.

I use it but I'm not sure it is necessary. I still have to pop them out sometimes.

You don't strictly "need" it. I use it on Lake Powell to talk to the gas dock operators or to call for mechanical help if necessary.

You likely need one if you do not have a digital TV, but if you do have digital TV, then this acts as an antenna to bring in the digital channels in your area. Place it in a window if you can seems to work better then. It is good for when you do not get local channels on your satellite TV like us! It can pull them in for you.

This is used to program the options in the brain/computer; assign, trunk, door, aux, etc to particular buttons. You can install the alarm without this, but if you have a digital display on your remote, it may be mislabeled when you hit certain buttons. And if the alarm goes off, your digital display may not show the correct triggers. Basically this is to reassign the inputs/outputs.

What Mr. Osborne said, you don't need this. The entire purpose of this item is to get rid of a magazine disconnect safety (aka- lawyer safety) that Ruger saw fit to add to the MKIII, but was not present on any of previous versions of the pistol. Since you've got a MKII, consider yourself lucky and feel free to laugh at those of us who had to get one of these to get our pistols to operate the way they ought to.

The purpose of this portafilter is to troubleshoot your grinding and tamping technique. If your technique is good you will see a single stream on the center of the portafilter. If it's not so good there will be all sorts of problems like secondary streams, squirts coming out of the periphery of the filter and an off-center stream. I had a lot of those issues and troubleshooting them one by one has improved my pulls greatly.
