HDHome Tracker Review
I would like various users experience about this tracker?
1. How do you personally rate this HDHome site as a HD tracker?(content,internal encode quality,retention,UHDs,Seasons packs etc?)
2. How do you compare it with other trackers like CHDBits,TTG, HDChina, PTer? is it better close enough than these?
3. How easy is it to get invite to HDHome than the above mentioned sites?
4. If i manage to get into HDH,is it enough for fast UHD,bluray contents than CHDBits etc
5. *Do they have assessments 2 times a year like in CHDBits, do higher ranks exempted from these test if its there?
6. What are the seedbox rules if any? common seedbox providers supported there?
7. How often do they open signups or give invites to users as i havent found hdh invite giveaway here in TI for a longtime?(how hard is it?)
**overall is it worth joining a single chinese hd tracker like HDH as i find it is easy to get that the top tier?

Thanking you all for your opinions, every ones welcomed!!!

When was the last time HDH opened?
