Leaving a 5-star rating wouldn't leave space for improvements. So I consider such feedback to be much valuable with higher indication to loyalty. The product is extremely great! It does the job to be done, with an exceptional and easy product experience. More improvements can be directed to:
-Including a camera glass front lens spare part.
-Improving the application UI/UX.
-In some situations, the Wi-Fi connection is lost without no obvious reason.
