Two thumbs up

It has been a great improvement to getting a good night’s rest. I don’t wake up every two hours to refill the water tank.

Great machine and works flawless filling up my CPAP daily. Takes the chore out of filling it up myself nightly and will keep water level at all times so won’t run out by morning. I recommend getting the extended tubes too place it on floor area as I also bought the tray it sits on and highly recommend that as well.

A Start Up Company that Stands by their Products.

The CSpring is a very useful tool for refilling the Remed 11 water chamber which empties quickly. I was unsure about buying this product since it was relatively new on the market. I went ahead and purchased it and after several months I had some issues with the water level sensors. I was blown away by the excellent customer service from Victoria U. and the company’s commitment to stand by their products and their commitment to customer satisfaction. She completely remedied the issue and took time explaining the varies components to their products. Based on this experience I highly recommend this company and its products.

Works nice

No more running dry at 3am. Nice and quiet. Nice unit. Connection plug for harness seems very fragile so I purchased extended warrantee today.

Makes life so much easier!

I can't go back to filling the water reservoir EVERY night! This machine is amazing. When I'm ready to go to bed I don't want to stop to mess with distilled water and cleaning up any drips off my furniture. This lets me get right into bed!

CSpring too the rescue

Have used it for the past week and outstanding results. Does as advertised and keeps a constant level in my CPAP all night. Would recommend to anyone who gets up multiple times during the night to refill, but it also takes away time from me filling it up before bed nightly. Construction is great and recommend getting the longer extensions as it helps in placement of the CSpring. Optional tray working out great as well. 5 stars ⭐️

Device works very well. Veery Satisfied, However, (including video) instructions were not thorough. The evice inside the container was loose and I was not sure where to put it or what its purpose was. Fortunately, I was able to consult a friend who already had one. Suggestion, put a water fill mark on the inside of the container,

Wish i had got one of these ages ago.

Such an excellent bit of kit, such a simple thing but takes such a massive headache out of the daily water filling routine and no more running out of water in the middle of the night. I have my humidity high so having it refilled automatically through the night is just what I needed.
Also i’m in the uk and i was a bit dubious about ordering but it was such a breeze.
Quick and easy. Very well packaged and tracking from day 1, it arrived exactly on the date and time given. Perfect.
One other massive thing was the customer service. Exceptional.. I couldn’t praise Victoria enough. She has been so helpful with my questions, nothing has been too much trouble. Outstanding.
So bottom line is, a fantastic machine and does exactly what it says on the tin, and with that customer service you just can’t go wrong.
Thank you.

Just what I needed

The extension hose was perfect, it allowed me to position my water tank next to my humidifier, side by side, with the water tank sitting on the left side.
The cleaning brush and sponge were handy too.
