The SQ40 is a solid camera that can't be described as little but does its job well. That said, the same reservations as usual apply - buying film is expensive and you're still subject to somewhat regular dud outcomes. It's chunkier than an Instax Mini and you do therefore get better photos in our opinion, but the added difficulty in carting it around means that I still think a Mini is the better choice for most people, on balance.
Nice new looks; Great film format; So easy to use;
No tripod mounting; Expensive;
