## Customer Reviews

### ⭐⭐⭐ Shipping was quick, product was well packaged.  Slow to saturate.
*by L***. on January 4, 2018*

I processed this slab into 4 x 4 x 2.5 inch cubes for use in a hydroponic growing wheel. It cut easily and was packaged nicely however I noted that when soaking the pieces prior to planting they were slow to accept water and I needed to physically hold many of the cubes under water for some time to insure they were thoroughly saturated.  Even after 3 or 4 minutes, air bubbles were still emerging from the pieces.  In contrast, the processed cubes I have purchased in the past typically will fill with water very quickly.

### ⭐⭐⭐⭐ Four Stars
*by A***R on April 13, 2017*

Good product, slightly overpriced.

### ⭐⭐⭐⭐⭐ Prime!
*by W***L on March 31, 2016*

It's great to see Prime offers on Grodan finally!  Thanks Amazon!
