Let me start by saying this universal remote is a lifesaver when it works, but getting there can be frustrating. I've used it with multiple AC units over the past few months, and here's my honest take.

The good: When it pairs successfully (like with my Toshiba unit), it's magical. The range is impressive - I can control my AC from across the room (about 8 meters). The LCD screen is clear, and buttons have a satisfying click. For basic on/off and temperature control, it does the job perfectly.

The bad: The setup process is needlessly complicated. Like many reviewers, I struggled with pairing until I found the right technique (hold SET until blinking, then keep holding). The Celsius-only display bothers some users, though personally I don't mind.

Pro tip: Don't rely on the included instructions. Instead, use this method that worked for me: 1) Turn on AC manually 2) Hold SET until codes flash 3) Let it auto-search until you hear a beep 4) Press OK to confirm.

Biggest frustration? Some functions randomly stop working. My remote occasionally refuses to adjust temperature despite perfect pairing earlier. Also confirmed not working with window units as advertised.

Final verdict: At this price point, it's worth trying if you need a backup remote. Just be prepared for some trial and error during setup. When it works, it's fantastic - when it doesn't, you'll want to throw it out the window!
