So far, the product is quite excellent. It serves the purpose we require and delivers upon our expectations. My daughter is a 14-year-old junior national team climber in Paris, France. We were looking for a simple tool that can easily be attached in our apartment ... a tool she could use before she heads to bed. We added the YY VERTICAL BOARD EVO and the MAX CLIMBING GRIPS HYBRID. The board is solid and even worked in our antique Haussmannian apartment, where the door frames are not perfectly straight. Finally, the shipment was very fast and the product arrived well-packaged and in excellent condition. Thank you.
