At first glance we may think this is not worth $25 but let's break down what we really get. Scan the QR code on the box and you're taken to a quick, but well produced instructional video. In the video Chuck does not push this tester on you. He even explains that you can build this yourself, if you prefer. He even says other leveling methods work just as well. Personally, I have used paper, feeler gauges, and micrometers. I prefer the simplicity of this, Go No-Go, tester and the results are great. The same QR code takes you to his included files to run the leveling squares tests. They run fast and show your results in record time.Exploring CHEP's channel on YouTube is where you find the real value. In a related video Chuck breaks down the simple g-code files and shows you how to modify them, easily, if you want to make changes or if your printer doesn't recognize certain commands. He has other leveling videos using paper, if you prefer, and another using a feeler gauge (better than that non-calibrated paper). Chuck has a huge list of videos that has helped me solve many 3D printer problems. There are also great hints, tips, and honest product reviews. He has many videos explaining Cura slicer settings. Chuck, and some of his viewers, also has spent lots of time developing and testing profiles to print much faster. He shares these profiles with us for free. I personally us one of CHEPs fast print profiles daily on my Ender 3 S1. It really works great and it saves me so print much time. Did I mention he gave it to us for FREE!All these videos are fairly short. The information is offered in a format that is very easily digestible and advertisements are minimal. Best of all CHEPs videos are kid safe and kid simple. No one is drinking, there is no foul language, and the information is explained in simple bite size pieces. So let the kids watch and learn.Back to the $25, we are not only paying for a battery, circuit board, a few cheap components, Chuck’s prototyping time, etc… No we are helping to support a really nice gentleman, who has been helping us, for years, for free. Buy one! You you will not regret it.
