Query: 1st bottle functioned great, but stopped spraying after about 6 weeks

1st bottle functioned great, but stopped spraying after about 6 weeks, with only minimal use (less than once a week). We didn't drop it or use inappropriate liquids or any of that. We didn't have trouble with mold yet, or it getting dry (altho we live in the desert). Contacted the seller abt the broken mist sprayer, and they very quickly sent a working replacement. We don't know how long the replacement will work, but the customer service is outstanding and we appreciate their responsiveness. Excellent!
