So far have use only once on an RV trip to FL. Rec'd a few warnings about temp but when we went to RV it was not. We are trying different locations throughtout the RV incase it was in a "warm" spot. Not sure if the sensor might need to be calibration issue, but I'll be in touch if we don't figure it out. It does give peace of mind that our dogs are not without A/C .

Have only used it one weekend, but it gave me such peace of mind leaving my puppy for the 1 hour we went to the pool.

I got this to monitor my dog when I have to leave him in the car for short stints on road trips - it's a plug in hybrid so I am able to leave the AC running but wanted to have a safety measure in case something weird happens and the car turns off. I tested it before any real life scenarios and it seems to trigger warnings at the right temperature as set. It is easy to set up and the folks at MarCell are very helpful and answer the phone if there is any confusion. The interface is not cute like their main competitor but it is perfectly functional and easy to understand, and the subscription if half the cost of the competition. Even with paying two bucks for an eight pack of instant temp reads it is great deal, given that the main expense of such devices is in the subscription. I did use some of the instant reads when I was first using it to make sure it was working, and still use them from time to time to spot check. At 25 cents per use that doesn't worry me, but you don't need them - can just trust you will get an alert if the temp exceeds what you set as range. Note you can use it running off the battery, it does not have to be plugged in. They say the battery lasts 48 hours so that is far more than enough for my purposes. I don't think there would be any way to know if the battery had died however so it would be prudent to charge it between every use if that's how you plan to use it.

Easy to set-up. Accurate info

Quality product and excellent customer service!

Very pleased-works exactly as advertised and great customer service

I have been running a marcell monitor for about 10 years. It is a very necessary item to have when leaving your home for an extended matter of time.

It's amazing! Gives me peace of mind while I'm away from my trailer for my animals. I can set a range so if the temp gets too low or too high to alert me and it also sends an alert if it loses power. I've had it now for 1 month and I'm extremely happy! I'm so glad I went with MarCell instead of the other ones I looked into.

Does what I need it to do.

Marcell is working as advertised.

I live on a barrier island where the power goes off quite often. It’s important for me to know when that happens when I’m away so I can take appropriate action. Since wifi gadgets depend on power (or an intact wired connection) for internet service, they are useless in this situation. With an internal battery an cell tower connection, the MarCELL sensor is the answer. Won’t save you from storm surge, but I got data right up until the house flooded from Hurricane Ian…

OK - I bought this product and hooked it up (I think!). Two weeks later I receive this survey asking "Have you received your MarCELL Pro Multisensor?". Now I am concerned. As far as I know, it is operating as it is expected but the company does not even know if I received it. This is a huge red flag for me and now I have to follow up on the entire setup. Once you set it up, shouldn't the company know if you "received it"?

Performs perfectly and good timing because we lost power from a storm and it alerted us to protect our greenhouse.

Well we haven't had a power issue yet, we are happy with the ordering process, delivery, ease of setup, and subscription processing.

Excellent !

It was exactly what I needed.

great assistance from agent on chat

Had a delay, and had to start order over again

Quick and Efficient!

very helpful that it gave details on the differences in the comparison when you hovered over it.

Problem with getting servy

Fantastic Product that super easy to purchase. Highly Recommend!

Great device wish I'd found 10 years ago. Mr main unit works great the water puck has limited range and was unable to place where it should go. Wish I'd gotten the humidity puk. Overall very satisfied. Customer support is great.
