"I cried when I saw my engagement ring after using this. It looked exactly like the day he proposed. I had no idea how dull it had gotten over 3 years. This thing is magic."

"I wear glasses every day and they were always smudged no matter how much I cleaned them. One cycle in this machine and they looked brand new. Bought one for my mom the same day."

"Bought this to clean my watch collection. Works perfectly on metal bands and gets into every tiny link. Saves me money every time I'd take a watch to be cleaned. Already paid for itself."

"I was skeptical it would work as well. It works exactly as expected. My grandmother's ring that hasn't sparkled in 20 years is sparkling again."

"I collect watches and have been paying a bit of money every few months to have my metal bands professionally cleaned. Tried Sparklr on a whim and honestly it does a good job. Got into every single link on my seiko bracelet. Grime I didn't even know was there. Already used it on 6 watches. Best $45 I've spent this year."

"Bought this as a Mother's Day gift for my mom who has a huge jewelry collection she never cleans. She called me the day she got it — apparently spent two hours cleaning every piece she owns. She said her diamond earrings look like she just bought them. Now she's telling all her friends about it. Honestly might be the best gift I've ever given her. Already ordered one for myself."
