I think that there is a lot of good advice here, but it's not directed at the OP.
They specifically said that they want their kids using Android for reasons that they don't want to get into, and have found $100 solutions.
Their question was, will it work, and the answer is yes.
Discussion with the kids, suggested alternatives costing more, and Apple vs Android is all fine and well, it's just additional to what the OP asked.
First rule of parenting that all parents know - never tell others how to raise their kids.
