Another Indiegogo marketing takedown.
Kara Pure raised $1M for a water-from-air dessicant dehumidifier that costs US$1800 uses a $20 alkaline mineral filter to give you tasty filtered water for the cost only 1400Wh/day in energy, at best.
So dumb it hurts.

Dave is a tad obsessed with making a 10,000hr battery life bench multimeter. It's actually not hard.

Dave fixes an LCD fault in a 1991 vintage Sony Pyxis IPS-360 GPS receiver.
Could there be other issues though?

Dave got hit with seven Copyright Content ID claims for background music used in his video, from a company called Adrev a.k.a "Adrev for Rights Holders"
UPDATE: A response from SmartSound. It is NOT their fault and they are doing everything they can to combat this problem they that is affecting them. So please do not put any blame on SmartSound.
------------------------------
Thank you very much for bringing this to our attention. We actually do not use AdRev, or any other company, for Content ID, but we do work with them to release incorrect copyright claims. Since all of our music is royalty-free, flagging our own music would be counter-productive for us. These claims do come up for some music in our library that was originally licensed from the original composer on a non-exclusive basis. This music is indeed royalty-free when purchased from us, but the composer may also be selling the music through other methods that are not royalty-free, and YouTube cannot tell the difference, so it flags the video. These claims are quickly released using the methods listed on our website here: http://www.smartsound.com/support/supportFAQ/#RFM_youtube
However, the music tracks that you reference in the video, "Clear Vision" and "Wild Chase", are actually owned exclusively by SmartSound and should not be in Content ID at all. In fact, these are 2 of the 5 free tracks that are included with our Sonicfire Pro software that anyone can download for free. It seems that someone has taken these tracks and uploaded them to Content ID and claimed them as their own and is now trying to collect revenue. We take this very seriously and are already working to remove the fraudulent claims for these tracks. SmartSound music is 100% licensed to be used on monetized YouTube videos, and even though Content ID will flag first and ask questions later, we have found that AdRev and other similar companies are usually quick to remove the claims when they are incorrect. Disputing the claim through YouTube never seems to get very far, but using the advice from the link above and notifying AdRev directly through the link in our FAQ should resolve the issue in a timely manner.
Again, thank you for bringing this to light. This is a case of someone fraudulently claiming our music as their own, and we will get to the bottom of it immediately. If you have any questions please feel free to let me know.
Best regards,
