Probro BESL25 12" Smart Christmas Ball Lights 3PK

I’m trying this new product out this holiday season. The globes are bright and very pleasant ascetically. Two issues I have: 1) Even when using the group feature in the hello fairy app, the timing between the two lights is noticeably off. No matter how many times I reset and turn on and off, one is always faster than the other. The app needs a microsecond delay calibration feature to ensure all devices stay in sync. 2) I was disappointed these globes couldn’t be grouped with the strawberry C9 lights that I purchased from the same vendor. It would be cool if the c9 lights I put throughout the house would sync up colors with these globes.
