There are god reviewers outside but let me give a note on this:
Lidar: Yes – really needed for flow calibration but its all about first layer inspection, Spaghetti and Errors discovery during the print. So, a lidar serves to getting off of the mobile app as much as possible at is own risk. If you want to provoke a first-layer binding error, apply a thin strip of lubricant to the base plate. Prints can fail and I`m not here to check always any print on my cell phone. If it can do the flow calibration – fine but that was never the reason way I got it at all. The best cell phone app is the one I never need at all - so the APP should always start with start scream like: Sorry, we apologize that you need this APP, we’re working on it. AI = I am no longer needed at all, everything else is not AI.
Technical reviews: Reviewers sometimes not that they are not technical reviewers - no problem at all 
However just because they do not check the accuracy of the printer they check much more which is interesting than those how just go along their standard procedures. On the end, every print will by optimised just to past their testings and my needs do not always fit to their procedures. Those who have the background for this are very, very rare and do it more for there personal imprufment - thanks a lot . Also thanks to the non technical Reviewers, they are importand too so thanks to them as well .
TPU - More and more people are coming e.g. flying drones or among other things. Statements about TPU are becoming increasingly important. TPU is form me the most important print material because its where 3D printing has already caught up very close with non-3D printing parts.
Put this thing in Parts: Well not many doing this and in fact one how does it is enough. Reviewers normally go to the next machine after a few weeks or month which is ok – but this do not mean that I as costumer never need to put this peace in part. There are Reviewers how note other reviewers how did the job and the video focus on exactly this matter. So the god reviewers highlight other reviewers as well. On the other hand, that would actually be exactly the video that manufacturers should actually do themselves. Not a single word, just completely disassemble and reassemble once or is something to hide there?
Feel free to add to this list, I won’t comment on anything. Everyone knows best what would actually be important to him and woulde have his own personal reasons for sure.
