some d bag stole my mouse at work (OG logitech trackball) so went looking for a replacement, noticed an expired deal that's back for $98 at officework.
I called exhibition st OW and they confirmed the had just received stock this morning.
Seems to be limited or no stock at surrounding OWs in Melbourne CBD.
Using this right now, has helped much more than I thought it would. Very long battery life and good for big handed people as well.
Only thing I found is you still tense slightly when gripping it which can flare up the parts you might be trying to rest in your arm.
