The EMR25 wins on paper - bigger battery, ultrasonic pest control, 12-hour runtime vs 8 hours.
But the EMR23 is the sweet spot for most people - it handles typical use cases just fine and saves you $30.
Here's what I found after testing both on 4 different camping trips:
- The new 180°C heating system is a real improvement (I'll show you why temperature actually matters)
- Both work well in still air, effectiveness drops in strong wind (they don't advertise this limitation)
- The ultrasonic feature on the EMR25 is hard to measure definitively, but seems to work
- At $119-149, they're expensive upfront but actually cost less than bug spray long-term
- Safety around kids requires common sense, not paranoia
The bottom line:
If you regularly deal with mosquitoes and current solutions aren't working, these are probably the best electronic repellers you can buy right now.
If you only occasionally need protection, stick with what you have.
I also break down exactly who should choose which model, address the safety concerns around kids and pets, and compare them honestly to Thermacell and other alternatives.
Plus: I'm giving away both the EMR23 and EMR25 (nearly $300 value) - just watch and comment with what you currently use for mosquito protection.
No hype, no affiliate pressure - just my honest take after real-world testing to help you make the right decision for your situation.
Let me know what you think after watching.
