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

Two negatives: delivery time and price. Ordered on April 20th and delivered on May 23rd, so regular delivery of this door alarm takes just over a month. During that period, the price rose 43% from $2.37 per unit to $3.40 per unit. It's still reasonable, but not as good as it used to be. The rest of the device works! Simple design and good quality. Place it under your front door for security. If someone tries to get in, the alarm goes off. This won't stop an intrusion, but it can deter an intruder and alert you that someone was trying to get in.
