Strange you should mention this 
My Look Solutions Unique 2 Hazer never used to have any smell to the haze. I then bought a new carton of fluid and that has that slightly burnt sweet smell. To be honest I thought it had gone off, so I bought another carton and that smells exactly the same. I think they've probably changed the solutions slightly. In actual fact I was going to drop Look an email to ask them.
I can live with it but I think I preferred the old solution with no smell.
Cheers
