I purchased this disc because I was intrigued by the fact the materials are sustainable and biodegradable, but I was bowled over the first time I played it.  It is one of the straightest flying discs I have ever thrown.  One of my local courses have a couple of narrow tunnel holes that would cause me quite a bit of consternation.  Now I use the Einstein and drive with much more confidence without worrying my disc will get gobbled up by the foliage.  It immediately became one of my biggest go-to's.  I highly recommend it.

As someone just starting out in disc golf (transitioning from ultimate), I really enjoy playing with this disc. I can reliably park it about 50-100ft off the basket which fits my needs well. It's stable on the forehand and it will hold just about any line you need it too. With me I find that it can be chucked pretty reliably in the 200 range from the FH. Haven't found much success throwing it backhand though (although that may be because I'm just starting out). The reason I didn't give this disc 5 stars is due to the fact that the durability with the bio-based plastic isn't all that great. Although it's a nice touch to have a biodegradable disc. It has its problems. It has developed a moderate warp after hitting a tree and has a couple of chips. I have noticed that the flight was affected slightly by this but it still will be a staple in my bag. I'd definitely recommend this disc to anyone with a good FH or BH who wants a stable, predictable workhorse midrange disc, and anyone just starting out!
