I have today the first part with the so-called extra strong velcro attached to the wall. Spontaneous impression: "Oh yes keeps bombig" So I thought. Short went shopping and behold, half the parts was already dropped. I do not want too bad judgment on the Velcro, because that keeps you really powerfully zusammen.Aber when the adhesive with which the belts are fastened no good, then even the strongest hook and loop fastener is useless. Therefore only 2 stars from me. Since Tesa has significantly rework.
