Purchased focusing on the large water tank it offers (600ml), after an unfortunate purchase of a rechargeable portable water flosser system with a small 150ml tank.
POSITIVES:
1. Large tank that holds 600ml of warm water and 5ml of liquid dental cleanser. At maximum intensity (10), it lasts for 2 minutes of continuous rinsing.
2. Many accessories in a convenient case on the lid.
3. Satisfactory power (from 7-10 on the setting).
4. Mechanical water stop at the handle with an on-off switch.
NEGATIVES:
1. Short water spiral, when pulled too hard it pulls the whole machine.. There are suction cups on the base, but they require a very smooth surface to grip and have little power.
2. With the water switch on the handle closed and intensity at 7-10, there is a risk of burning the pump, as the water cannot circulate.
OVERALL, I don't see the reason to get the original one for 120€, when there is this copy at 1/3 of the price. You try it and see how it goes. Anyway, mine, with daily use, has been working fine for 1 month.
