I found the unit cleans well but the lens buckets get warm when set to clean for 5 minutes. Also the lens buckets need to be dried after each use of they will deteriorate and perhaps rust.The lid hinge is very poorly reinforced, my hinge broke about 2 months ago on the lid side, just not enough material I think. A stronger hinge with stainless hinge pin would be a much better design especially if you travel with the unit, which was the main reason I bought mine (to do away with chemicals and the TSA confiscation thereof).I found the battery can be replaced easily and should be available on Amazon by model number, the lid should also be made available, it is not at this time.

I wear monthly contacts so by the end of the month they usually don’t work too well but with the help of this cleaner it is like they are new every day. It is quick and easy to use , it is worth every penny.

I was excited by the idea of this product because it sounded like a great idea for cleaning contact lenses. I was disappointed to discover the the frequency is very low and does not appear to be anywhere near ultrasonic. To my ear, it is about 2 pulses per second and the lenses don't appear any cleaner coming out than they were going in. For now, it is just a big and fancy contact lens case.

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.

I got the model with one button. It was working great, it cleaned contacts like they were new. I was excited to see how long I could make my monthlies last; a yearly set of 12 is >$100 so I try and stretch where possible. I recommend everyone to use Opti-Free contact solution. One thing about the device I don’t like is the size of the reservoirs are shaped so that you use up a good amount of solution. Why not a convex shape?Anyway I went to use it for the 3rd time and it already stopped working. Green light blinks on then off. Won’t charge. I plan to email support (a Hotmail .eu domain, let’s see if I get a response) but come on, how does this even happen? Battery issue? From the reviews the lifespan to expect from this device is only a year, and that’s already abysmal

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!

Works well but battery recharge life is short. Once week to start, down to every other day in less than a year. Lid hinge broke. I still use it because the ultrasonic feature is a proven successful technology. I will probably buy another one anyway unless I find a better one.

I purchased this to replace another brand that broke shortly after I bought it. This one is much better quality and works great.
