I set the master print as my thumb, and if I don't put it just right, it wigs out and I need to wait about 10 seconds for it to recover.. I may be doing something wrong, but hey, its a lock, how hard can it be..I have had it in my gym bag for a couple of weeks and try to unlock it each time I leave the gym ( I'm using my old combo lock for now). I have been able to unlock it every time, but it can take a few tries. I want a lock that works like my smart phone for this price. one or two tries and I'm unlocked. so, this probably won't be used unless I can somehow figure out how to make it work quicker and more consistently.Updated: Seller contacted me and offered assistance very quickly which was nice. Hopefully we can figure out how to get it to work quicker. ### ⭐⭐⭐⭐ Lock failed after three weeks *by C***G on Reviewed in the United States on February 21, 2018* Update: the seller has sent me a replacement item and it has been working fine.Great concept bad execution. The fingerprint part took a little while to figure out but it generally works fine, within one or two attempts. The mechanism that is supposed to hold down the cable on top of the lock gave way after less than a hundred cycles used on a locker. Upon examination, there is a thin piece of metal that sticks out and stops the end of the cable from pulling out. That flimsy piece of metal failed and would not hold its position. I'm buying a more sturdy padlock style replacement. ### ⭐ I was unable to get it to work and I returned it! *by R***4 on Reviewed in the United States on February 25, 2018* This is my second fingerprint padlock; I brought the same lock with a different brand name and I had to return it because I could not set an administrator’s finger print. This lock had the same problem: I tried different fingers and none of them worked. Without setting up an administrator’s finger print the device doesn’t work. I really wanted this lock to work and I am disappointed that it didn’t. I envy those who received a lock that worked because I believe this is a great concept. I returned the lock for a refund. --- ## 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.th/products/63529938-fingerprint-lock-smart4u-small-biometric-padlock-keyless-waterproof-for-school](https://www.desertcart.co.th/products/63529938-fingerprint-lock-smart4u-small-biometric-padlock-keyless-waterproof-for-school) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
