We have professional engineers to develop products suitable for global markets and provide 24/7 technical support.
Minimal radiation levels that are significantly lower than the increased radiation generated by phones struggling with weak signals.
No, the repeater amplifies existing weak signals but cannot generate signals where none exist.
3-year warranty covering manufacturing defects (excludes man-made damage and natural factors).
