• Night light to see the unit in the darkness
• Great feature of control panel lockout
• Efficient full indicator light
• Amazing 8-hr sleep mode

Cons

• It’s hard to keep track of your cat elimination habits as you see since you will always see the litter box clean and it's quite dangerous.
• the current price is high
