I cannot think of any negative ponts at this time.
I research a lot of grinders and I thought this was the best choice in my price range.
I did consider the Solis Maestro Plus but I read that machine created too much static electricity and it created quite a mess with coffee grounds flying all over the place. I have not experience this what-so-ever with my Infinity.
I bid on a brushed chrome on eBay and I got it for a steal; $99 plus $10 for shipping - total $109. The brushed chrome retails for $190 and regularly sells for $139.
The brushed chrome looks great with my kitchen and has been performing flawlessly and is quite easy to clean.
The grinder is easy to dial the right grind and it is a world of difference from my old Braun blade grinder. I have been using this for my drip coffee maker and I feel that it could handle an espresso grind with ease.
Great buying experience. I bought it on Ebay for $$99 plus $10 for shipping. The grinder was delivered promptly in about a week.
