After use, my opinion is rather mixed.
Most of the unit:
- Easy handling (even for a small hand);
- Flash quantities;
- Mains connection;
- Speed of use despite the small size of the flash;
- No pain!
The - on the unit:
- Connection thread really too short, you have to sit near a power outlet;
- No possibility of the instructions before buying and also some surprises reading ... (not taking certain medications or doliprane before use) so WELL read the instructions before use.
- No changes observed at the hair after the second use.
I will return to this comment in 4th use.
