I am currently using the Critter Love Complete and my ladies seem to be thriving. It is my understanding that the owner of Critter Love has quite a bit of knowledge about sugar gliders.
I have 3 ladies all in the same cage who also bicker over the food and so far, (knock on wood) I haven't had an issue.
If it makes you more comfortable, drop Peggy an email (from her website) and voice your concerns or call her. She is very helpful and nice
