Mechanical vs Air Locker

气锁是最可靠的，电锁次之，for a daily driving 4x4机械锁很伤车。


Just by what I have read so far, mechanical locker is the simplest one which avoids air hose/compressor or
electrical wire. So I thought by design it should be
more reliable than AIR locker.

Am I wrong on this?

The most popular Mechanical locker, OX, seems pretty
tough and the only problem I saw so far is the wire needs to be routed carefully.
