DONGSEN Portable Auto Ultrasonic Contact Lens Cleaner Case, Fast Vibration Lenses Cleaning for Daily Care Device

Though the product came on time and the seller sent a thank you message for my order, this product is very cheaply made. There are 3 components (power cable, contact lens accessory case and the machine) wrapped individually in plastic bags with the actual cleaning machine wrapped in a different sealed plastic. The plastic on the machine portion felt like it was self sealed with a sealing gun and gave the impression that someone returned it before and that they resealed it and sent it out again. The machine portion itself sounded like a small plastic piece had broken off inside as there was this rattling noise. The inside tray used to house the contact lenses is very awkward to use. Getting the contacts into or out of the tray is difficult. The cover that goes over the portion where the contact lenses and tray insert does not snap into place or do much at all. If you jolt or accidentally bump the machine, the cover can come off or fall off. I couldn't really tell if the machine cleaned my contacts or not. I heard it turn on but no visible small vibrating waves that you would find in an ultrasonic jewelry cleaner. I was really disappointed and returned the product immediately .After sending the product back, I did some research online about ultrasonic cleaners and some cleaning hacks for your contacts. This product is extremely overpriced for what you can get with an actual much more powerful ultrasonic jewelry cleaner. This is what I would recommend after some online research and researching ultrasonic cleaners. For essentially the same price point and if portability is not a key selling point, buy this Magnasonic Professional Ultrasonic Jewelry Cleaner with Digital Timer for Eyeglasses, Rings, Coins (MGUC500) it's on Amazon Prime and has over 3K reviews majority positive. The Q&A portion of this product has a number of people saying they have cleaned their contacts using this product. Simply rinse your contacts out with the contact cleaner of your choice, fill the machine with water at it's instructed level, then place the contact case with cleaner and lenses in the machine and set the machine at the time you want. I can say that I was able to use a pair of contacts that were at the end of their time and beginning to feel grimmy. After using this machine that felt almost new again. The Magnasonic's ultrasonic waves were strong enough to make it through the case. I think it's a shame that this product is selling at the same amount as a very well reviewed, well made, larger ultrasonic cleaner is.

Feels like new after each use!

I have no issues with this and my contacts feel better cleaning them once in a while with this.

not working

Been using this product for weeks now. Very satisfied. I really like the size, it’s very portable and cleans my lenses very well.

I wish I would have had one of these sooner. I can use my contacts longer now and save lotsof money. I can feel a big difference when I use it. and when my contacts need to go for another swim

nice products! After Clean my contact lenses it was so comfortable ！
