I have one of those and I've tried it with two different chinchillas. Neither of them really took to it. It's about useless unless you hold the base down and it's made of plastic so I'd never want to keep it in my chin's cage where it can be chewed and the pieces swallowed. Not good for rodent insides. I do have a vertical metal wheel with a solid running surface (highly recommended) though and Kulu loves it especially at night. It makes him quieter when I am sleeping because he'll be running on that and not banging around jumping from shelf to shelf. I rigged up a digital counter on it and he'll log around 6,000-8,000 revolutions per day. That's over 1.5 miles. I do recommend getting a wheel larger than 14" but the one I have is good for my 500g male.
