Ease of use

Haven’t tested it yet

This is easy to turn on, and you can even do so with it still in it's heat sealed bag, which even has adhesive foam on it. You just hold the on button down through the plastic for 5 seconds and you get a confirmation light that flashes periodically to let you know it is working It's compact, too. But I won't know if it works, or specifically if it works in the temps it will be subjected to in a hot car until 200 days from now - it is single use.I feel like I should have bought one to try out and read in just a day even though that would be wasteful to be sure I know how to get these working properly before running a 200 day test.

the instructions are simple - turn on, turn off, plug, play UNTILsome refuse to turn onsome refuse to turn offthe one that did turn on, and 60 days later, turn off did not download any data

Compact, accurate, good lifespan:This product is very compact and easy to fit into a bunch of different container types without taking up too much space. The thin design of the product in particular makes it easy to slide into place, and the devices are decently durable and can withstand environments of varying temperature ranges without incurring damage. The product has been pretty accurate and is a very valuable tool when transporting materials that need to stay within a a certain temperature range (food in our case). The data output is simple to comb through and provides a very good picture of the temp fluctuations. The 200 day range is pretty good just be aware these are one and done, so you can't reuse them after use.Overall, this is a good product and I would recommend.

Every three months, I have to get my blood drawn to produce serum tears, requiring 14 vials that must remain cold during transport. Using a shipping cooler with enough ice packs ensures everything stays at the right temperature, and the temperature logger provides proof that the vials stayed within range throughout the journey. The temperature logger is super simple to use and once you plug the logger into a computer it shows up like a USB memory stick and the files are all there to be access and then analyzed for a full report of the temperature during the shipment. This way, the lab can no longer say the samples arrived warm, as I now have evidence they were kept cold the entire time. It also saves me from the hassle of having to provide another 14 vials of blood.

So far these have reacted exactly as described: Push the power button more than 5 seconds (I am guessing it took closer to 8-10 seconds) and the blue light flashes telling you it is activated. I am planning a 180 day run on these, so we'll have to see how much data actually gets logged. 2 of 2 that I have used so far are working as expected...the rest will be used in the next few months. If I have any longevity or logging issues, I will update my review, but for now, considering price-point...it's a definitely recommend.
