Broke after a few months of use, now it won't even turn on

I'm on my third unit and I will buy another when this one breaks down because despite the eventual failures this is still convenient and effective. This has been my experience: 1) First unit, 4 months in: The hinge broke and the lid separated. I had to buy a new one. Fix: Right out of the box, lay a narrow strip of duct tape across the hinge to reinforce it. 2) Second unit, 2 months in: The UV bulb partially burned out. On activation, the bulb came on to full brightness but then, within a second, dimmed to half brightness. The bulb should come on and stay on at a consistent brightness level. The sonic cleaning process doesn't rely on the UV bulb, so I continued to use this unit despite the bulb failure. 3) Second unit, 10 months in: The start button stopped working consistently -- the unit would turn on about once every 5-10 button pushes, and eventually stopped coming on at all. I bought a third unit. 4) Third unit, 2 months in: Going strong. Hinge is reinforced, UV bulb is bright. Why I keep buying it: It is very well designed for cleaning my retainers and keeping them safe and out of sight when I am not wearing them. I use plain tap water (no cleaner tabs or mouthwash) and the sonic cleaning appears very effective -- even when I brush my retainers before putting them in for cleaning, the left-over water shows debris that has been detached from the surface. This is exactly what I want. I don't know what difference the UV light makes but I can say that my night-time retainers that I've worn for 5 months are squeaky clean. During the day I keep my retainers in the empty cleaner where they stay dry and out of the way. This unit does take up some bathroom counter space but it is more space-efficient than rectangular sonic cleaners and doubles as a discreet retainer keeper as well. I gave this five stars because I find it very effective to clean my retainers and no other sonic cleaner is as space-efficient as this one.

I’ve used this to clean my Invisalign retainer about 3 times a week for 4 months. Sometimes I also put in the head to my electric toothbrush. I’ve always put in one of the Smile effervescent tablets or a less expensive “denture cleaner” tablet and my retainer is always super fresh and sparkly clean after about 5 minutes of bubbling and UV light. I’m glad I read reviews before purchase to be aware that the lid breaks off rather easily so I’ve been super-careful during set-up and wiping out the machine after use. Despite my care, the lid is starting to crack at the hinges so I’m not sure how much longer it’ll last. But considering the price of this is MUCH less than competitors and its really good performance, I’m very satisfied.

I've worn retainers to sleep every night for about 13 years, and I was looking for a way to prolong their life. Honestly, it could work but I really can't tell - at least comparing them before and after and to the videos I've see online of other products that showcase the same benefits.
