Great contact sensor! Versitile installation. *by C***R on Reviewed in the United States on August 18, 2016* I ordered the plunger style, then realized I didn't have room to mount it as per the instructions! The install was on a door where the hinge side was butted up to a "fake door" with lots of glass. No way to drill a deep 1/4-inch hole in that! Instead, I mounted the unit on the latch side of the door, which changes from a friendly plunge action, to a slightly more harsh sweep-action. So far, it works fine, since the square edge of the door rides the dome shape of the sensor to depress it during door closure. Time will tell how long it lasts.Otherwise, install was fairly simple. 3/4-inch Forstner bit is great, but the 1/4-inch hole for the antenna is trickier. You will need a LONG bit for that (>6 inch), since the chuck of the drill gets stuck in the 3/4 hole. I didn't have one handy, so I used a 3/8-inch blade style with an extension. that works fine, and keeps the 3/4-inch intact to contain the device.Pairing was a snap, and I can confirm it works with the VIVINT panel. I set it up as a "DW21R recessed door contact" and the panel learned the code just fine. Pro-tip: pair and test the device before you install it. :) ### ⭐ not a good product *by D***S on Reviewed in the United States on September 22, 2018* there is a delay when you one the door with these plungers. If I open and close the door fast enough it doesn't even tell the alarm. too bad I already drilled holes and installed them because I would go back to my wireless thin sensors. ### ⭐⭐⭐⭐⭐ Install and forget. Perfect! *by B***R on Reviewed in the United States on June 19, 2017* I have a few a these throughout the house, covering all doors. I used the included shim as needed on certain doors. The installation could not be easier if you have the right drill bit. I did have one fail with a bad contact (wouldn't always send a door opening signal intermittently), but that door was used an extreme amount of times over several years. I replaced it without fail - battery life and range is great on all of them. I wouldn't hesitate to recommend this sensor for door use. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/22526836-plunger-wireless-door-security-sensor-2gig-plunger-2gig](https://www.desertcart.co.uk/products/22526836-plunger-wireless-door-security-sensor-2gig-plunger-2gig) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
