Latches do not matter with this. It's very sturdy when installed and will provide resistance for intruders. Packs away nicely into a suitcase or handbag. ### ⭐⭐⭐⭐⭐ Felt safe, secure and relaxed! *by K***D on 17 June 2026* Ordered this having seen it shown on TV, absolutely impressive 👏 I went on a solo trip using this for my Hotel room it made me feel safe & secure where I could relax which is fantastic for a single female! ### ⭐⭐⭐⭐⭐ Good, but the instruction booklet is incorrect *by P***N on 11 March 2026* Seems to work fine, worth £25 for the peace of mind after a recent report of illegal entry into a woman's hotel room. Tested on our wood floor, the emergency release works well too. However, the instruction booklet is wrong. It says turn to the left, ie anti-clockwise, to tighten & to the right, clockwise, to loosen when in fact you need to do the opposite, clockwise to tighten, anti-clockwise, to release. ## Frequently Bought Together - DoorJammer DJ3 Portable Door Lock Brace for Home Security and Personal Protection | Hotel Room, Apartment Safety, Travel Door Stopper | Easy Installation, Compact Design - AceMining Portable Door Lock Home Security Door Lock Travel Lockdown Locks for Additional Safety and Privacy Perfect for Traveling Hotel Home Apartment College - Original Trustella Heavy-Duty Portable Door Lock - Stainless Steel Security Device for Enhanced Safety - Ideal for Home, Travel, Hotels, Apartments - Silicone Protector Caps Included (1, Black) --- ## 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.hr/products/104197554-doorjammer-dj3](https://www.desertcart.hr/products/104197554-doorjammer-dj3) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-19*
