I purchased tactacam 2.0 solar panels and they simply could not keep up and completely died after 2 months. I switched to Herd 360 and the difference is remarkable. I put my camera out at 50% charge and solar panel as it came out the box and within 48 hours everything was 100%. The size and quality is beyond impressive. Herd 360 is my choice forever.
Edit. I hit 4 stars by mistake, wish I could give 10! By a landslide best bang for your buck! ($ and pun intended)
