Attention not suitable rolling code remote control if ... !!!! and not specified by the seller

Product arrived quickly, well packaged, BUT NO BATTERY NOR ANY NOTICE !!!!
Product design, but is useless !!!
The remote does not work at all with my garage door, OR WITH THOSE are PROTECTED by a "rolling code" (no programming possible and no possible duplicates, as protected by a non-copyable code)

Disappointing, no serious and no professionalism, the seller does not state that these remote controls are ineffective with remotes and boxes door garages that are protected by rolling code !!! (Why sell the product or the description is vague and or buyer will be found fooled by its purchase ????)
I'll buy another one with a professional ([...]); it will work, will be compatible with my electric garage door and will be supplied with 1 battery and instructions in FRENCH!
I prefer to pay the price, have a good product that works, that is guaranteed, but at least I would find myself not like a fool in front of a bogus product, which brews the wind!
An investment that goes up in smoke, damage .... and disappointment for me!
