Helps cracking.
I’ve been laying concrete for many years now, you can always which pads have fiberglass, and which ones do not. Fiberglass helps cracking significantly. With the cost of construction these days, this is a worthy investment.

Good quality, varied length
What I received is good quality product of varied length. The box contained exactly 10.0lbs verified on a calibrated digital scale. Product is well packaged in 2 layers of resealable bags The length of the strands do vary a bit and should really be listed as 3/4" or less as they are between 3/8" and 3/4". This will work for the driveway grass pavers I am making. I would prefer the strands had all been 3/4" for better strength. I knocked off 1 star for the varied lengths. Overall would buy again as the price was under four dollars a pound, and a pound goes a long way.

Cheap way to improve concrete properties
I'm pouring some small concrete pads around my house. The pads are small (about 4" x 3' x 6') so I don't need steel reinforcement. The fiber is a great way to reduce micro cracks, increase impact strength, and improve overall durability of the concrete pads. I found this one at a great price for it's size and weight. Highly recommended for anyone who wants to do small concrete pouring projects around their house.

Quality material
Good quality fiber, very easy to mix up as long as you don’t throw in a whole clump. Make sure you break it up before you throw it in your concrete.
