This boxing machine is great all around. It is incredibly fun to use. The build quality is outstanding. The materials are of solid sturdy build as well as it has the perfect size surface area for jabbing. It looks and feels great. The functionality of the lights are bright, easy to see, and have a quick response to your jabs. Love how they make a light trail to each pad to be hit as well as light up white after a successful jab. It allows for single, double and triple jabs in the progression of the songs and or training mode. Speaker quality is great with loud clear sound. This machine is easy to use and understand how to plug and play. The included accessories are great to have and use as well. The gloves are very nice and work great. They are a tad big for small hands but to be expected they are made as a one size fits many. The output voltage for a power supply is 5V with an absolute minimum output of 1.5A. Input voltage per customer service is 5V 2A. This product is a great value for the price. Fast Shipping as well and Great customer service if needed. I’m so glad I purchased this boxing machine and I would love to have another one for a family member who would love to own one as much as I am loving mine. Great Product!Thank you Haigang!
