For the price I got it for (15 euros plus 3 shipping), it is truly worth it. It grinds perfectly even frozen fruits. I often make protein smoothies and add frozen strawberries or frozen mixed berries. It makes everything really homogeneous. Of course, it doesn't grind the seeds from the strawberries, but neither does the much stronger blender I have. I haven't tried it with chia seeds or other similar seed ingredients as I personally don't use them in my diet. It grinds nuts (I have only tried putting them in alone, not in a smoothie with yogurt or milk or another liquid base), but it doesn't make almond butter, for example (generally, it doesn't make nut butters). It turns them into flour and then struggles. Also, it's harder to clean the pitchers after grinding nuts. Along with the device, two pitchers come, one of 600ml and one of 400ml. It also comes with a lid that you can put on the pitchers after mixing the ingredients, so they automatically turn into a water bottle. It's very convenient to drink the smoothie you just prepared this way. However, I should note that the spout on this lid for drinking is somewhat small, and you can't drink very quickly. Also, the little cap that fits on the spout doesn't seem particularly strong, and if you put it in a bag, it might open (I haven't tried it and probably won't). It's perfect for the fridge, though. Also, the little cap doesn't open 180 degrees but only 90, which is a bit annoying in some cases when drinking. Generally, you get over this last problem, though. The blender gives off a plastic smell when you first use it. The pitchers need a good wash before the first use, at least two washes to get the plastic smell out of them. The pitchers are not suitable for putting hot liquids in them and cannot be put in the dishwasher according to the instructions, which are only in English and Bulgarian. There are NO instructions in Greek (as there should be since we are in Greece). Finally, it should be noted that nowhere on the box does it mention that the pitchers are BPA free. I don't know what BPA is, but I mention it because it's stated on some other plastics. The pitchers are plastic (obviously, for the price). In conclusion, it's worth every euro and does an incredible job for its price. I am very satisfied and happy with my purchase and recommend it to anyone looking to spend this amount on a blender. I don't believe you will find another with such power (300 watts) and two pitchers. It looks sturdy and like it will last, but only time will prove that.
