After struggling with a dead remote for months, this replacement finally brought my Goodman AC back to life! The green backlight is super handy for nighttime adjustments – no more fumbling in the dark.

The compatibility claims are accurate (it worked perfectly with my R51I4/BGE model), but be warned: some users report needing to adjust the battery springs. I got lucky – mine worked immediately with fresh AAAs.

What impressed me most? The range! I can now control my bedroom AC from the kitchen (about 25ft away through walls), which the original remote couldn't handle. The button layout is intuitive, though the plastic feels slightly cheaper than OEM.

Pro tip: Double-check your exact model number before buying. While it claims universal R51 compatibility, some mini-split owners report issues. The seller's customer service seems exceptional though – they apparently send free replacements if it doesn't work!

The Celsius/Fahrenheit toggle works flawlessly (perfect for us metric-system learners), and all standard functions (timer, fan speed, swing) perform as expected. Just don't expect premium build quality at this price point.
