[问题] Double Size Garage Door Openner?

[Martin]

新房的Garage是可以停两辆车那种的。选购Garage Door Openner的时候应该买1/2 HP的还是3/4 HP的呢？

另外，Chain-Drive的跟Belt-Driven的比较，除了噪音大一些，还有别的缺点么？

谢谢

3/4 :blink:

3/4 HP is better.

问了一个朋友，他家用的1/2的好像也没什么问题...

3/4 HP would last longer. The gears inside the box are made with plastic.
