I purchased it for a car for the second time and it will be a second purchase, but I am interested in COSPA being excellent. Although it is not sound-like, it is satisfactory to compare with genuine if it is sufficiently usable.
I expected disappointing sounds, I was disappointed with ordinary light sounds. I think that it is difficult to express in words when selling, but if you do not know without buying it, I am scared and can not buy it.
It is firmly made to price. Since it is just installed, it is unknown about durability, but unlike cars, it is installed in places where it can easily be exposed to rain so worry about rust problems.
