Every time you turn it on, it takes 1 to 2 minutes for the controller to sync with the console. The sticks can fall back and drift very easily without doing any damage to them. ("Drift" means the sticks move your character without even touching the stick.) Battery life is poor, but if you have a LONG charging cable, this shouldn't be an issue. Controller buttons and triggers work properly and PS4 recognizes them as legitimate controllers. Overall, these are GREAT controllers for a kid who might not feel as comfortable with a $60 ego controller, but not for an adult with dedicated gaming sessions. Spring.
