Question I need to buy a replacement mouse any suggestions on what I should look for?

It CAN'T be ambidextrous aside from that what should I look for?

Since you did not list anything like what you actually like in a mouse, what it's for, or your budget, you should look for a mouse that exists. You may want to provide a bit more details or just do a web search on "how do I pick a mouse" and read some articles. Many variables in picking a mouse, first how much you can spend, size of hands, grip style you like, how many buttons you want, curved or flatter shape, wireless or wired, quite a few things to decide first before looking for advice.

I have the MX master 3 for my office. I love it and now i understand why a mouse can be so expensive.

If you are looking to game on it this mouse won't be a great choice. I don't think it would be fast enough.
