The Selfie-rod can be extended by means of telescopic rod and has even at full extended bar and large, clamped Smartphone stability. The Bluetooth function is in such an apparatus indispensable and works very well - the connection to the mobile phone is very fast and works reliably.
I personally have tried the jig with a Samsung Galaxy SII and HTC One - ie a rather small and a slightly larger smartphone. Both times were both phones safely and securely in the device.
Recommended funny and practical product!
