I like that they are very professional, have great customer service and provide excellent work at fair prices for their clients. Nothing really to dislike about this software so far! They also offer free consultation sessions which is always appreciated by our team as well because we can get feedback from them then decide if it's worth pursuing or not with other providers in mind (we usually end up deciding against some of those). We use thinkmobilestudio mainly due to its flexibility when developing AR/VR apps - especially VR games where you need more than just 3D models but actual game logic implemented into your app too (think Unity vs Unreal Engine here).
