What are the dimensions?

Thanks for asking. The fermenter is about 14-3/4in tall and 9-1/4in wide.

Is it exactly 3 gal or do i have extra space to compensate for the lees so I can fill the secondary perfectly?

It is exactly 3 gallon to the ring below the wide mouth it is a nice fermenter but thin plastic advise using a carrier.

Yes it is. I have 5 of them and very satisfied

Can this be used as secondary fermenter? Any drawbacks?

There’s no reason it can’t technically be used as a secondary, but I’ve read it’s not great to use plastic secondary for an extended period of time (over a year) due to the alcohol contact.
