I checked lot's of reviews from my fellow buyers and I saw that the product has some negative reviews in the past. But they're eagerly addressing it and improved the tool drastically. I chosen tier 1 and I didn't checked the tool right away. I tried the tool weeks after the deal gone. And my first impressions were, didn't bought a higher tier.

I will surely upgrade to a higher tier, if the deal comes back again.

Pros
1. Have lots of good ready to use avatars.
2. Lip sync is good (not the best, need improvements in native Indian languages)
3. Adding lots of new tools (improving regularly)
4.

Cons.
1. Tier 1 & 2 are basically non usable and tier 3 costs dearly.
2. Needed improvements in processing speed (constantly showing upgrade to speed up banner)

Due to tier 1, limitations I didn't get a chance to fully utilize the tool yet. Anyway I am going to keep it and in future surely upgrade to higher tier, if the deal comes back.
