There are already reviews of the shirt iron here:
CleanMaxx Iron for Shirts & Blouses
I think the shirt iron is great until it breaks down. I'm returning it today after 9 shirts.
But the said 9 shirts are really smooth in my opinion. I smooth the button placket before and after. The collar and cuffs are not perfect but I think they are sufficient.
I haven't been able to test the trouser press yet because the machine gave up the ghost too early.
The quality is rather cheap but the result is top.

For me, it also only lasted 9 shirts in the first week....
and I wouldn't praise the result like others here. On the one hand, 10 minutes per shirt is too long.

And on the other hand, anyone who praises a car that breaks down after 90 km has, in my opinion, not fully understood what a car should be able to do...

Does anyone have any long-term experience with the appliance? Will it last long if you iron a shirt every day?

I haven't tried it yet, but check YouTube, I've seen several films there. All of them were very positive. On the other hand, if the quality is not right (Andy_Wuest), then we have a problem.
