It does not have an on/off button, which the AI of Skroutz claimed it had. It is a good and economical choice that is definitely worth its price at around 20 Euros.

Very good and powerful. Large, you can grill meats as well. It grills very well and evenly. Its downsides are that the plates do not come out, so cleaning becomes more time-consuming, and that it is a bit bulky compared to typical toasters

Good toaster.
You can grill quite a few things, as long as you find the right temperature.

it's the best...big enough for three to four small toasts comfortably...toasts incredibly quickly etc...I haven't tried it yet on anything else

I have it for almost 6 years..without any problems!!!!! and it cooks evenly and crispy. It opens 180 degrees and you can grill meats..the plates are non-stick but they don't come off.

TL;DR: It grills souvlaki/burgers satisfactorily, but the problem is that it is difficult to clean. However, for its price, it is fine.

The plates are not detachable and after a few months, the non-stick coating obviously deteriorated. Now, for cleaning, I have to warm it up a bit to soften the fats and residues, unplug it to avoid any accidents, and rub the plates with a damp cloth while they are still warm. It's a hassle.

I have had it for 2 years and it works fine, but I am looking for another one with detachable plates. If you plan to grill meats, I recommend the same. Of course, for something like that, the price almost doubles. You get what you pay for.

It is as the product description says. Strong, nice toasting, crispy bread. My only objection is that devices like this are not suitable for grilling.
