Eurostar SC250D Gas Bathroom Heater: Comparing with Junkers, Functionality, Failure Rate & Cost

There are so many stoves on the market that you can get lost. Can any of you professionally involved refer to the euroStar SC250D bathroom heater? Apparently our native production. How does he relate to the Junkers. A model worthy of attention, what is its possibility, failure rate and all? How much is a new copy. Apparently it has an innovative heater. I would very much ask for this knowledge. I was offered to buy. It is known that the seller is widely praised and I want to be satisfied with the purchase.
Thank you in advance.

The construction of all new furnaces is practically the same. Is it worth paying extra to a more branded one?
The decision always rests with the investor

Thanks. Wise words. I thought there were other values behind this.
