The amount of sounds i was able to find for my little animation project was nice, and easy to find.
However, as a single person working on a hobby, 15$ for 5 sounds or 29$ for 20 is a bit steep...
If i had more money i'd get the 249 year bundle, which would pay for itself after 160 sound downloads, assuming you otherwise use the 29$ option (unless my math is wrong)
Some reviews mention 'lulling customers in' with promises of free sounds, there is a free sound section, but i havent checked it out, so im not sure the scope of it.
Sound quality is very nice and very varied, so if you need just a few particular sounds you cant find elsewhere, it's a good option.
