I have been using this for almost 2.5 years now and love it. I purchased it because I ended up with a 30 day soft contact lens and was having trouble getting it cleaned, there seemed to be more and more build-up. Not only that, when rinsing in in the palm of my hand and trying to rub off debris with my finger just didn't seem like the best way to go about handling to lenses. Not sanitary, not consistent. I tried multiple cleaning options before finding this and have never looked back!

It cleans on a charge for 2-4 weeks - I just re-charge after two weeks out of habit. Great for traveling!

It is suggested that you don't leave your contacts in the metal lens holder part overnight, and just use this in the morning before you put your lenses in. So I put them into a plastic case and switch in the morning for cleaning. When it's all done -and you can choose 2 or 5 minute cleaning time- the case gets wiped dry and put away. I have never had any rust and have to say in 2 1/2 years of wiping my case down after using, rust won't be an issue.

It's also QUIET!
My husband went with an updated version where the plastic contact case actually sat inside of a unit similar to this and just asked me to buy him one of these. The other case was so loud it sounded like somebody was running a water pik or electric toothbrush for two minutes! And he didn't feel like it cleaned his lenses.
There may be a newer version of this case, and I would have no issue purchasing another of this style from the seller. 5 stars from me!

Very easy to use and does seem to clean my contacts . My only complaint is the cleaning cups of bright steel make it very difficult to see if contacts are in them.

Easy to use and is good quality.

Before purchasing I asked my Dr about ultrasonic cleaning and she poo-pooed it saying it was a hoax. I wear RGP scleral lenses after my cornea was damaged in cataract surgery. The lenses are molded plastic and sit on the whites of my eye so they are big. I have been dealing with streaks on the outer 1/3 of the lens that makes them suck air under lens. This blurs my vision. The first night I did a 5 minute cycle with the left over water after Clean care disinfecting my lens the night before. I skipped the step where you rub the lens with Optimum. I could see the "streaks" float to the surface producing a clean lens. I alternate to 2 minutes every other night. It seems some lens deposits are protein, some are fat. I don't know the difference. I do know that this one time purchase does far better at cleaning my lenses with less hassle. I highly recommend giving it a try. I costs less than 2 months of the scrubby stuff with less friction on the lens.

This ultrasound contact lens cleaner cleans the tear proteins really well. I use it to clean the soft lens and scleral lens.

The 2-min daily cleaning works well, and the 5-min weekly cleaning also warms up the solution (for some reason). Maybe it cleans better when the solution is warmed up.

The lens well is pretty small and shallow, so it doesn't take up too much contact lens solution with the cleaning.

If you use it for the hard lens like the scleral lens, be careful because it can scratch the hard lens. So I usually put a soft lens underneath to cushion the hard lens so it won't rub against the metal case that can scratch the hard lens with the vibration. It is costly to scratch the scleral lens.

I thought the lens well is tightly sealed with the plastic case but they aren't water-sealed. Eventually, some solutions seep into the inside of the case and started rusting the steel case. You can see the rust stain around the edge of the lens well and the plastic case. There is also a small crack in the plastic case too, where you can see the rusts coming through the crack line. Eventually, I think the leaked saline solution ate up the wiring or the electronics. The battery finally failed to recharge, and the unit went dead after about a year of use. I was disappointed that it died when it cleaned the tear deposits well for my soft lens.

But it doesn't clean the tear deposits for the hard lens as well as the soft lens. I had to rub the hard lens to get the tear deposits off, but it doesn't work well even if I tried to rub and rinse it, or ultrasound it multiple times. The only way to get the tear deposits off is to use the Clear Care oxy-clean solution to get the tear proteins off the lens.

So there can be improvements to make it better if they use stainless steel or surgical steel that doesn't rust or use plastic completely for the lens well. The case should also be completely water-seal tight to prevent any saline solution seeping into the inside of the wirings or electronics if it were to last.

It cleans well for the soft lenses but no so much for the hard lenses. I wish there is something better out there to do a better job than this.
