Review on 🚨 Trademark Global Door Stop Alarm – Portable Door Stopper with Siren for Home, Hotel, or Dorms – Adjustable Sensitivity Settings, Black, One Size by Adam Huper

The price may be right but shipping is the slowest in the world. The product itself will not work properly if you are on a carpet. I would only recommend it for hard floors. Adjusting sensitivity doesn't really affect performance. Makes a piercing but not too deafening noise in the same room. If used in the basement it wouldn't be too noticeable upstairs. If you do not have problems with long waiting times for delivery from China, then the price corresponds to your request. It seems that the same product is sold on sites at a much higher price, but then how much is it worth waiting for its arrival than paying a little more and getting it quickly.
