This is an older basketball goal our sons used . Lifetime closet model is a 46 inch version @ 146.00 at Walmart. Elevation is changed manually in 6 inch increments from 7 1/2 feet to 10 feet. Portable on rollers. Issues. Initially had water and then sand in the base to keep goal upright. When moving had difficultly getting material out so had to slit base on two sides. See photos. Black material came back and realligned. Also backboard is polycarbonate. Look at last picture where weather over time cracked the polycarbonate. Small crack. material still present and backboard still works well.
