FANTASTIC!!!  THIS IS THE SECOND CRATE I HAVE BOUGHT IN THE LAST 2 MONTHS BECAUSE I HAVE 2 BIG 4 LEGGED  GIRLS.  IT IS SO EASY TO SET IT UP!!!!   I LOOKED AT IT WHEN IT WAS COMING OUT OF THE BOX THINKING NO WAY....BUT IT IS  INCREDIBLE!  SETS UP IN MINUTES!!     STRONG, MOVES IF YOU WANT TO CHANGE ITS LOCATION....OR PUT BRAKES ON THE WHEELS IT STAYS IN ONE PLACE.  AND I SAY THIS BECAUSE MY LAB FOUND OUT SHE COULD MOVE IT ....ALL BY HERSELF!!!  PUT THE BRAKES ON AND SHE TRYED TO ROLL IT...BUT NOPE!!!  DIDNT BUDGE!!  THIS LAB IS AN ESCAPE ARTIST... BUT NOT WITH THIS CRATE.   BREATHING A BIG SIGH OF RELIEF.....  I WILL SAY THAT I WILL HAVE TO GET A RUBBER MAT FOR AT LEAST HALF OF THE BOTTOM AREA WHERE SHE STANDS BECAUSE THE GRATE BOTHERS HER FEET.    WONDERFUL PRODUCT!!  THANK YOU!!!!!!
