This was very easy to setup and use right out of the box. In less than 10 mins it was in the tank! The data logging function is very handy and takes a reading at intervals you determine. Seems to be stoutly built and has a long cable. You will definitely need something long to lash it to keep it stable/upright to get good readings. I used an old blinds adjustment rod but I do know there are different items out there that will hold it in place. At first use it has lived up to the hype. Fast shipping too!
