Stop in for a cup of coffee

So I need to drill a bunch of holes about ten ft up on side of metal building thru tin and girt. Great place for a mag drill. Dewalt is 900 Milwaukee is even more. Vevor from China is less than 300 bucks. All of them are 10 amps. Anybody have any experience with the brand? Vevor? It is a one job only tool purchase in my mind. Lord knows it should be able to do thirty holes before it dies right?
