It came in a timely manner and worked perfectly. Thanks ### ⭐⭐⭐⭐⭐ Effective and reliable, great price here on Amazon *by P***E on September 28, 2025* I've been using these clocks in the HVAC industry for over 40 years. Intermatic while not flashy or groundbreaking technology they are a faithful and reliable performer. Simple to update in place and very cost effective. ### ⭐⭐⭐⭐ Does what is expected at time of install *by A***R on February 22, 2021* I had an electrician install this for me since I don't do hard wiring. It was pretty basic since it was replacing an existing Intermatic 4-5" square timer that I had had for 30 years at least. Bad reviews on the current exact replacements so went with this. Installer had no problem at all getting the wiring done easily. It's located inside my garage to operate my front porch lights. Unless it quits on me prematurely, I give it a 4 out of 5 stars so I have some wiggle room. In less than a week of operation, however, it's doing what it's supposed to do, at the time it's supposed to do it. Directions seem fairly straightforward and I reviewed them before the electrician left and everything worked accordingly. --- ## 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.in/products/8876651-intermatic-t103-24-hour-mechanical-timer-switch-120v-dpst-indoor](https://www.desertcart.in/products/8876651-intermatic-t103-24-hour-mechanical-timer-switch-120v-dpst-indoor) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-21*
