NAILGIRLS 60W Cordless Rechargeable UV Nail Lamp - Professional Wireless LED Nail Dryer with Metal Base, Fast Charging Gel Polish Curing Light, 3 Timer Settings for Salon, Home, Travel & Manicure Parties

Pros: It's large enough to ensure you don't bump or damage your design before curing. It has 42 lights, and claims 360’ curing. My experience indicates that's probably accurate.The removable bottom plate is metal making it both reflective which I think helps in curing your nails from all angles, but it also makes it easy to disinfect.The timer has several options. You can set it for 30, 60, or 99 seconds. The 99 seconds mode is called a “Smart Progressive Mode” and gradually increases the wattage from 40W to 50W and ending at 60W. Once set, it'll default to that level until reset. It automatically recognizes when you insert your hand and turns itself on/off after the set cure time. You can also turn it on and leave it on. The timer indicates how many seconds the light has been engaged, and counts up until you shut it off.You can use the unit plugged in, or charge for 1-2 hours and run it in battery life for 2-4 hours.Cons: None that I could discern.Honestly, I love this lamp, but I'm not a professional. I have three teenage daughters, and learning how to do their nails made for a fun bonding experience. I can't attest to the things a professional may notice. However, for a person who does a set of nails every week or two, this lamp was a game changer. I love it and would highly recommend it.
