Endurance Training Stretcher Compound Device Massage Men's Bracket Kit Physical Increase Size

I was excited to receive this device for its intended purpose ; however, I used it once and noticed a crack in the plastic main frame that supports the metal threaded bars. Also noted was that the thread direction on opposing sides of each bar are set in such a way that the bar will separate during adjustment. This results in the pre-loaded springs ejecting out of the bottom section thereby making it impossible to use. Additionally, the spring tension is much too high for this delicate application. I would be cautious about buying this product.
