After the driver leaves, please immediately open and inspect the items themselves. If you find any damage, contact us with the following:

  • A photo of the item unboxed with the damage visible

Right temp every time

I used to guess temperatures, now my steaks come out medium rare every time. Super easy to put on my Sunstone grill and the reading is always right on.

Eli O.★★★★★June 29, 2024
Accurate and well made

I take my BBQ seriously and accurate temps matter, low and slow or searing. This gives accurate readings, feels well built, and has held up great so far.

Noah★★★☆☆July 20, 2025
Does the job, nothing special

Works like it should and gives me a temperature reading. For the price I expected it to feel a bit nicer or do something more. Basic gauge, gets the job done.

Julian G.★★★★☆October 18, 2011
Reliable and Easy to Read

I'm really happy with this thermostat. The numbers are clear and easy to read, even when the grill is hot and smoky. It's a solid, reliable addition to my Sunstone outdoor kitchen setup, ensuring my food cooks consistently.

Eduardo Y.★★★★★July 18, 2013
Can't grill without it now

This really improved my grilling. No more burnt edges or raw centers. Very accurate and feels durable. Recommend it.

Q
How hard is it to put this thermometer on my grill lid? Need any special tools?Asked by Sunstone Support Team
A
It's pretty easy. Usually you drill a small pilot hole if there isn't one already, then secure it with the included nut and washer. A standard drill and a wrench are normally all you need. It's a quick DIY upgrade on most Ruby gas grills.

Q
Will this work on my older Ruby Emerald series grill?Asked by Sunstone Support Team
A
It fits most Ruby gas grills, including a lot of the older Emerald series. As long as your lid has a standard thermometer port, or enough flat surface to drill a new one, it should fit. If you already have an opening, measure it first just to be sure.

Q
What's this thermometer made of? Will it handle the heat and the weather?Asked by Sunstone Support Team
A
It's stainless steel with high-temperature glass. It handles the heat inside the grill and resists corrosion from rain, humidity and sun, so the readings stay accurate.

Q
How do I clean this thermometer and keep it accurate?Asked by Sunstone Support Team
A
Wipe the outside with a damp cloth and mild soap. Skip harsh abrasives so you don't scratch the glass. Check the mounting nut now and then to make sure it's snug, especially after big temperature swings. That keeps it accurate and keeps moisture out.
