Works, CADA brand, 3/5. 

Problems with the battery and remote switching itself off. The remote's battery terminals are weak and it is advisable to put a rubber/plastic underneath to avoid losing contact with the battery and this will partially solve the problem.

Buttons only on-off, not adaptive.

Battery life on a single charge ~50min.

The package contains:

• 1 x rechargeable remote control
• 1 x rechargeable battery
