ET Motor Gate Nice(Far from Nice, A Big Headache)

We purchased a ET300 gate motor 3 years ago and since installation we have had nothing but problem after problem. If its not the control card that has to be reset its the battery that has to be replaced. Since these gate motors run off a 24 volt battery they are expensive to replace and not easily available. Now they tell me that with the last episode I would have to replace the control card and the transformer plug and of course another new battery!!!!!!!! The cost of R2500!!!! I would not recommend this absolute ******* of a gate motor to anyone!!
