I have a similar one.
They are very expensive to run.
I mean very expensive. Mine is 17 years old
Now and it very temprental and works very rarely
It must have cost me in exess of £50000.
And from a performance point of view the
I have relpaced it with an electric one these are cheaper and more reliable.
Even though I have replaced it the old garage door opener
Continues to cost me money and heart ache
It is difficult to dispose of. I have sent it away
To the military and they have succeeded in making it better
But it is still costing me money.
So be careful think long and hard because
A garage door opener is for life not just for Christmas.
