The only thing that sucks is the compressors tbh. Everything else is pretty solid. Some unique effects in here that I would say are worth it on sale. For 99 dollars? nah. I find myself reaching for these quite a bit whenever I'm doing some sound design stuff. I think I got this for around $5-10.
No, they're not top sounding, they are good though, and some of them are actually quite clever. You can get better sounding alternatives to at least some of them for free. If you are on a budget and can get them on sale, I guess they are pretty good.
For the price (usually on sale for about 40€ or less) you get very high-quality effects. The only thing missing is a Parametric Visual EQ like the stock one installed in Pro Tools. Otherwise this collection is essential for you if you want top-sounding effects.
