The Brothers Brick is a popular LEGO website for adult builders and fans of LEGO

Here is an exert from their product review here

“The Box4Blox basically pre-sorted my 18 gallon tub in a little over an hour and greatly simplified the rest of the job. Now, when I have some spare time, I can grab one of those bags and quickly sort it out. I don’t have to take on the whole heap and I know that each bag contains specific kinds of pieces.”

“Overall, Box4Blox easily surpassed my expectations. Not only is it a good product for keeping the kids’ bricks sorted, it also has a definite place in the Adult hobby as a pre-sorter. I recommend it.”
