I typically use a different track ball guided by thumb both tend to make my hand feel retarded if not used for a while.....

A bit confusing to program and get used to reading.

Not the best, but not the worst by far. Having to get used to it, but it is well worth the money.

It takes a while to get used to it.  I gave it as a gift to my Dad he had a lot of fun shooting .25 paint balls at a target.

Awkward, takes getting used to and kinda bulky and heavy (relatively)

So far this is working well for me. The instructions are very difficult to follow and at first navigating around the settings and controls was difficult and not intuitive, but now that I'm getting used to is, it's starting to make sense. I'm not the only one who found the instructions difficult - two other people operate the same unit and couldn't figure it out. But after I got more experience with it I was able to make a simple list of instructions for the other two, and it's working well for us. It has capabilities way beyond what I'm using.

It does take a couple of days to get used to having the device "in" your ear, but once you get used to it it is very comfortable.  I often forget that I have it on.  Calls are very clear, although when talking outdoors the wind can make it difficult for the other party.

It is hard to get use to(I keep hitting the up arrow key instead of the shift) and also it sometimes takes a little while for it to respond.

There is a learning curve to this product. Once you get the hang of it it works quite well.

I absolutely hated this at first.. After about a week I got used to it and I LOVE IT! Glad I gave it a chance!

I like it, takes a little bit of getting used to compared to the old style. A little pricey, but a good piece of equipment.

This product does what it says, but it can take some time to get use to the changes from previous versions.

Takes some getting used to, but does a good job of spreading the diatomaceous earth.

Takes a while to get used to. The backside of the strap was a bit stiff and uncomfortable the first few times I wore them but has been getting increasingly comfortable with each use.

I've been using this for 20 minutes.  I admit, it's a little odd to get use to, but willing to give it a long try.  Next step will see how it works with gaming
