Super as a substitute for Dorma Hs 43

So I must say that I was really verunsichtert when I have read the negative reviews. I have nevertheless decided to use the product (Thankfully!) Because the original Opener Dorma HS 43 measly 70 costs. Priceless for me as a student.

The installation went amazingly well! It then once everything wunderba worked for 2-3! I was very surprised of it, as I have read from other reviews of a hour-long procedure.

Only the "Instructions" (if one may call the above) may not be trusted! Since then is something of constant blinking, if you put the unit in the learning phase. But it flashes more than 4-5 very quickly. This I missed on the first try, of course, and promptly serviced estimated 5 min.

In summary, super part, only by the poor "manual" actually 4.5 star !!! But it can recommend to anyone !!!!
