Nice device, but actually it is a bit fake (as with all these types of products). I saw (1) a review about rattling after 1 year. For me aa 1.5 months. Returns are no longer possible after 1.5 months. So repair and that will take 3 months (who knows). So doing something yourself is easier and, above all, much faster. The cause is that the rod is not oiled and then becomes stiff after a while if you do not use a lot of oil for blending. LEARNING POINT: Pour olive/sunflower oil into the neck (a little). Especially if you often work with vinegar/lemon because it dissolves and rinses away oil. If there is no oil in the neck, the mixer will run rough and the engine will warm up much faster, it will smell (but not defective, it must be very hot). It is quite a job to find out where all the click connections are to open it. The internal design is so that it also rattles easily. everything is loose inside. I'm not surprised it rattles. So everything was secured with tape and foam in between, which helped a lot, but not everything is gone yet, but it is much better now. What also doesn't help is that internal parts are made of POM plastic. When it gets hot, it melts or deforms, which can cause rattling (but does not immediately destroy the device). The motor is not oiled and has bronze plain bearings (so no ball bearing). A 220-240v DC motor (PT-7912). And look it up: at 14000/10600/6500 rpm. 0W / 120W / 240W. So how is it 1200W. Well, it does not have 220Vdc but 275Vdc and with turbo 295Vdc. That gives at 10600 rpm. 800W / 1026W (HIGH/TURBO) instead of 120W. How that is calculated to 1200W... then you have to start mixing thick syrup with that thing. So for normal smoothies it is really no more than 1000W. I've had a good look at it now. So that's fine, but I don't know if I would buy it again. But, another brand will be exactly the same. So the question is whether you will get something better/decent there. YOU GET WHAT YOU PAY. So I expected to get something more solid for those 120 euros.
