Its worth it in every way. I just stick it in the machine every morning, and it automatically runs in the afternoon, and I have a clean machine in the evening. When I went on vacation for a week, I didn’t bring it, and I developed a cough and a nosebleed.
They’re good but pricey. Setup not too difficult, I needed to purchase a separate adapter for the humidifier. Overall, it’s worth it knowing you have a clean, sanitized cpap every night. Plus you don’t have the hassle of cleaning supplies. No more vinegar or soapy wash. If you’re on cpap therapy and utilize your machine, I’d invest in it.
