Initially rated three to four stars because the fort wasn't sturdy. After reaching out to the company for building tips and determining it wasn't user error, they promptly sent a new set. Not only did they send a replacement, but they also followed up a few days after delivery to ensure satisfaction – and it was indeed satisfactory! The new set was easier to build and exceptionally sturdy. Exceptional customer service is rare these days, especially with online purchases. Thank you for your outstanding service! I wholeheartedly recommend it with a 10/10 rating.
