Great, until it broke after 1 use
**Update: After posting my review, the seller reached out to me almost immediately to send me a new blue light free of charge. I'm very happy with the customer service and can't wait to keep using this product as it was the brightest blue light I've bought and so amazing for the price.<br /><br />Used it once and worked great! However, after rinsing it off once, water got into the battery part and immediately rusted and stopped working. I only had it for maybe 12 hours before it broke. Definitely not waterproof like advertised. I would consider buying again however because it was the brightest blue light I've bought!
