They broke while I’m Working-out. DO NOT WASTE YOUR MONEY. The website is not available to replace or return the order so the warranty thing is fake.

Not worth for 8000.

I received this product with great anticipation and moderately high expectations. The design is solid and I was impressed with the results (serious muscle activation) after my very first workout and second. Unfortunately, on my third workout, one of the yellow bands broke.In my opinion, this should not happen based on the design unless inferior materials are being used for the band. Each rubber band is covered/protected by an expandable, non-elastic fabric sheathe or sleeve; this sleeve naturally (and I presume by design) limits the distance each band can be stretched by the fully expanded length of the sleeve; the only way to stretch the band beyond this limit would be to to tear the sleeve. In my case, the band inside of the sleeve snapped in half with the sleeve completely in tact and now offers no resistance!So despite success on the design and function front, I have to give this low marks since product engineering and durability seems abysmal and destined to render this product useless in little time.Disappointing for a product that's marketed as a "...highly durable performance system..." :-(. Hopefully this part will be replaced under their product warranty.* Update *I was contacted by the company and provided a replacement band under the product warranty without any hassle. It means a lot to me when a company is willing to stand behind it's products/services; for this reason, I have increased my review to a 3 star rating. If the product and/or warranty support holds up for the duration of the warranty period, I'll give it 5 full stars.

Fantastic. I had been using the rubber band style of resistance bands around my ankles for a few weeks, but obviously you can't kick very high or it slips up your leg. With this product you can kick however you choose due to the way it fastens on your legs. Tried for the first time yesterday, and got a fantastic workout. I use both the ankle and thigh straps, and pretty much keep them on my whole workout--which is a mixture of stretching, MMA, and weight-lifting. The thing I really like is the way the thigh bands connect to the front and back, which gives a very balanced, comfortable feel when you are wearing. Both the ankle and thigh straps stay on very well, and the clip-on resistance bands are of a much higher quality than I expected. I say that because for the relatively low price I wasn't expecting much, but am pleasantly surprised at both the quality and functional design. As far as results, all I can say is start using resistance bands on your legs. I have already felt a massive improvement in my kicking and stance just from the rubber band style resistance bands, and I can tell this product is going to take me to a new level.

This is everything we hoped for. My daughter is going to use this for running speed training PLUS...We are going to use the yellow bungees on a homemade power batting harness (saved $105 vs buying the "official" one!!). I had already made the waist wrap and ankle wrap for that, but you can actually use this almost right out of the box for softball batting (and pitching) strength training too - just connect the velcro on the thigh straps together to go around waist (unless you are skinny and can get a single thigh wrap around the waist like 4 girls on our team!). You would need to sew a nylon foot loop on one ankle strap (no big deal - just cut a piece off a Dollar Tree dog leash and sew it on. The extra loop won't interfere with any of your regular speed/strength training in the "as designed" use for this kit).We were looking at using regular Lowes bungees for the batting strength trainer, but open hooks would be dangerous. These are perfect with closed hooks AND cloth protective covers in the event the inner elastic were to break. Awesome!!! So happy with this item and its many uses for softball training.
