You get what you give. It's for a few things, not very strong when it goes into the liquid (water or coffee). Moderate satisfaction.

It consumes batteries very quickly, resulting in being uneconomical. It offers portability, for example, for camping, but it is not suitable for everyday household use. Get an electric mixer instead.

I don't know if it works well because I couldn't unscrew the device to put the battery inside! It should have mentioned that it requires unscrewing, and I tried with two screwdrivers, obviously it needs a very small screwdriver. In the end, I got frustrated and threw it away. It is very cheap indeed, but not practical at all to operate.

As I was washing it, water got inside the batteries causing everything inside to rust and lose all its power.

The button is pressed very hard and is a bit uncomfortable.

If you want something very cheap to take with you to make coffee for a month, it's okay.

Very thin axle, not well secured. Result: it wobbles in a circular orbit, as if it were crooked. Maybe you accept this, due to the low price.

Unfortunately, wasted 3 euros. I had to return it. That's why I don't like it with the bars. Because the motor is very weak, the mixer gets easily stuck with the slightest resistance and essentially doesn't work. Let's go for electricity.

Disappointing.
It wobbles off-axis from the first use. It struggles to mix froth (cold or hot).
It's better to get something of similar price from IKEA

In the first use, I realized that the spring on the head comes out as soon as it starts rotating inside the milk, and after a few seconds it smells burnt. Yes, it is a very cheap frappe maker, but still not worth its money.

For the price, it is amazing. Very convenient for coffee, frappe, milk foam, chocolate, and other beverages. Quite powerful motor. Just what you need for home use.
