If you search for the Hamster Heaven, you should get plenty of results about it, reviews, mentions etc. It meets the RSPCA minimum requirements (last time I checked) so it should be OK, but I'd wait for someone who's had the cage to offer some insight and wisdom into the suitability for Syrians.
EDIT: Here's a link to one of the more recent reviews. I'll find a couple more .
