After much research, I bought my H last July. Initially, after finding this site, I knew I made the right decision. Then, disparaging comments started coming in and I began to worry. I had never experienced any negative issues; Performed as advertised. This was a big improvement over my Iris+, even though the Iris+ can do some things the H cannot. I got real concerned after the mid September updates. I waited and finally installed ver b23. Again, absolutely no issues. If I just got lucky that is contrary to many past experiences, I ususally get the lemon. Three flights since the up grade and I am still thrilled with my H.
