It is the second one I am buying after finding it for 29€ (last piece), also the following text will be long.

First of all, let's make it clear that it does not crush ice, it does not grind raw meat, it is not for dough, it is not for mixing eggs.

Anything you want to put in it that is hard (e.g. cooked beef, carrot, apples, almonds, cucumber) should be cut into as thin and small pieces as possible (the instructions say 2.5 centimeters) and almonds, cashews, etc. similar types of dried nuts, should be broken into smaller pieces.
It also struggles with hard vegetable stems, for example the edge of lettuce, so you cut them off and leave them out.

For those who want to make protein shakes, it would be good to put half of the amount needed and after mixing it once or twice, add the remaining doses, so that it does not get muddy and stick to the sides of the bottle.
Of course, the mixture you use also matters. If you want to make something with yogurt, first put the liquid ingredient (water, plant-based milk, milk) and then the yogurt. Not the yogurt first.

A negative aspect could be that the measuring cup that comes with it measures in increments of 200ml, meaning 200, 400, 600 and in 10 and 20oz, which correspond to 300 and 600ml respectively.
The smallest one that comes as an extra measures 150 and 300ml and it also shows 10oz, while the maximum capacity (up to the point where the lid screws on) is 400ml.

The noise compared to the classic ones is moderate to low, meaning it won't bother someone who is nearby when you use it, but it will likely be annoying if you use it at night when everyone is sleeping.
In case something you put inside gets stuck, you don't even need to remove the cup to shake it, just unplug it and shake it as a whole or even turn it upside down and shake it. It is also lightweight as a device (1 kilo without the measuring cup), neither its capacity makes it "unmanageable" or heavy.

It has small suction cups at the bottom that can be useful for stability.

It is not like the multi ones that have more watts and are for grinding food and larger quantities. Yes, it can grind, but that is not its purpose, which is why I mentioned that the pieces should be small and thin.

Its dimensions are negligible, so you can place it anywhere in the kitchen without it being bothersome. For those interested in its dimensions, it is less than 18 centimeters in height (without the containers) and 12 centimeters in length and width.

The main cup that comes with it has slightly fogged up over the years from the inside, probably from the hot water when I wash it. The other one, which has not even been used a third of the time, remains as it was when I bought it.

The power button is not meant to be pressed indefinitely. The maximum duration is 2 minutes according to the instructions, which means that if the pieces are thick, it should only run for 1 minute.
I use it for 30-60 seconds, with a small pause corresponding to the duration of use I am doing.

When I first bought it, it was around 40€. Now I see it for 45, but either way, prices have gone up for everything.
I hope you found this useful.
