As I had some spare time and as no one else has reviewed it, I thought I'd review the Fop Duffy. A very good cage, sadly both of my Duffys have been purchased second hand, so I didn't know the retail price, but have found out it is around £30.
Size wise the cage measures 58cm x 32cm x 26cm, so not that bad in my opinion. This cage is suitable for all adult Dwarfs except robos, and is definately suitable for Syrians. Due to its height there may be wheel placement issues; sadly, like most cages on the market, the wheel is woefully inadequate for a Syrian with it only being suitable for a four week old and below. This cage is also easy to stack and can fit on most shelves.
Overall a good cage with the following pros and cons:
Pros
Suitable for a Syrian and all adult dwarfs except robos
Good size
Stackable
Easy to clean (takes me 10 mins)
Cons
Expensive compared to other cages on the market of the same/similar size
Unsuitable for robos
Low height means might not take a Syrian sized wheel
Unsuitable for bar chewers
Unsuitable for breeding dwarfs in
