Help buying vertical mouse


It has to be wireless. Budget it 3k-4k.

I've looked at the Zebronics Zeb Shooter, but the company does not accept returns, so I don't want to risk it.

On Amazon, I've looked at the Anker Vertical Mouse, but it's too expensive (>6K!).

One decent option is the Microware Vertical Mouse at 1.7K, but it only has a 3-month warranty and I'm not sure if I can return it if I don't find it comfortable.

All suggestions welcome. Thanks in advance.
