I have it for many years, maybe 7-8 or even more. I have made many attempts to cut straight satisfactorily, but still, you have to constantly be mindful and of course, you will never have a perfect result. For small tasks, it's okay because it doesn't take up space and it's lightweight. It does indeed easily break the ribbons, and I don't buy ready-made Chinese ones from the market, but from a large store in Piraeus where they make it for you at that moment and use high-quality blades, targeting professionals. But still, I buy them three at a time and take them for reattachment if the length allows it.

As another user of the tool mentioned, whatever money you will spend on ribbons, you will spend it to get something better.
I have had it for 2 months and I have spent 75 euros on ribbons, they break in the middle, every time I start it, I tremble in fear that the ribbon will break.
And it's not the adjustment's fault because I have checked it thoroughly (with measurements, leveling), the tool is faulty, I WOULD NOT BUY IT AGAIN.

The amount of money needed to buy ribbons (and it's not the tension or anything else) is what you would spend on a better one.

Guys, it's like a keychain!!! So, if you want to do clean, purely amateur use... buy it. I have made three very large cages with one ribbon! You need to have patience in cutting and slowly advancing the wood because the motor should not be forced. I would suggest to someone who has not worked with a professional large ribbon to pay close attention to the tension of the ribbon and its front-back position on the wheel. Don't have it working continuously for a long time, as it has a small motor. In conclusion, if you are not malicious, if you want it ONLY for amateur use, if you have patience... buy it. It's worth the money for what it offers because then for something better, you go to much higher price levels.
