Pros: don't buy, you never understand this product

Overall Review: cheap is always cheap if you buy don't expect to work nice

Pros: can work with the finger

Cons: too much problem with the bridge, have to be connected very near to the lock, like a few inches, not good because my near outlet is about 3 feet and I have to use an electrical extension to resolve the problem if you have the outlet a few inches from the entry door is good for you

Overall Review: don't buy if you don't have the electrical outlet a few inches from the entry door

the seller holds things in the mail office for more than 3 and 4 days as a requirement, for that reason return what I bought from him
