RS 1 I should have taken the other reviews seriously. The smells and side effects mentioned in the reviews of others is what I experienced.I opened one container and noticed a bad smell. I assumed it was just one. But I opened others that also had a bad smell. Gel nail shouldn’t smell like that! Against my better judgment, I used one that didn’t smell as bad. A terrible mistake.Halfway through doing my nails, I had a headache. By the time I was finished, the fumes were stronger and I was very sick. I had to stay in bed the next day.I removed the nails and contacted Amazon customer support. I told the rep that there’s something toxic in this product and it could pose a danger to others. The rep said that Amazon would investigate.I’m surprised to see that this product is still listed. This product isn’t safe and should not be used. It’s better to pay more for a known brand than to risk your health.
