This kit is rated for 800psi only which is suitable for automotive or window systems (a professional home air conditioner kit is rated for 4000psi). vacuum in the system. It looks a bit cheap, but it's very accurate for the price. The case is a bit impractical as you have to disassemble everything (including the hook) to store it. The handles are plastic on the sides and look like they will break if dropped. Still a good indicator for its price. It's good for casual use. I hope this review was helpful for your purchases.
