Fragile kit

Subject conforms to the image but actually, it lacks particular strength. Plastic cracked from the first dismantling (performed by even me) and broken after a week of use. The factory is not very good. Highlights of small pieces of plastic studs beyond, which sometimes damages the elastic when removing the strap, and can also injure fingers. However, by removing them with a nail cut, this solves the problems.
I can recommend the object to teenagers can handle the fragility of this object because beyond that, this kit fulfilled its primary function. For younger, I strongly advise to avoid generic or orienterai my choice to the full plastic kit (without disassembly possible). There are already a number of possibilities without having to put them in parallel pads.
The record is sketchy, as most of these kits, but there are lots of tutorials on the net via online videos to user blogs.
Positives:
The elastic are good unlike many that I could buy. They are solid, no unpleasant odor of oil, and have no fault.
Beyond the light quality of the kit, the seller is serious. The delivery was made very rapidemment and a little intention towards the child was slipped into the envelope.
