I have the igloo and it is fine. As with any ornament you can do a 24 hour soak before adding to tank. I use ornaments off and on and most with no problems. If has knock you down chemical odor after soak I wouldnt use. Most stores will take something back if have receipt and explain problem. I like Gingerbread house too. Might get one if they have good black Friday sale.
