## Product: Stelpro SWT2F Thermostat
**Brand:** Stelpro

## Pros
- Works perfectly with wall heaters, especially those that require specific double-pole thermostats.
- Compatible with single-pole wiring setups where some other thermostats fail.
- Installation is very easy, quick, and straightforward for a line voltage thermostat.
- Features a positive off switch to prevent the heater from turning on unintentionally.
- Durable and well-made construction suitable for garage or attic fan setups.
- Provides reliable heating control comparable to more expensive brands.
- Can be useful in troubleshooting heating issues by isolating problems with older thermostats.

## Cons
- Temperature calibration is often very inaccurate, sometimes off by 10 to 20 degrees.
- No manual temperature offset or adjustment to correct calibration errors.
- Functions more like a simple on/off switch than a precise thermostat.
- Installation instructions and markings can be unclear and unhelpful.
- The dial temperature setting does not always reflect the actual temperature accurately.
- Some comparable thermostats, like Honeywell models, have significantly better temperature control and accuracy.

## Bottom Line

If you need a basic, reliable wall thermostat that’s easy to install and built tough, the Stelpro SWT2F does the job well enough, especially for garages or attic fans. However, if you require precise temperature control or accurate readings, this model may frustrate you with its poor calibration. Consider looking at a Honeywell thermostat for better temperature accuracy and more refined control if precision matters to you.
