I bought two of these slides. Since they are also available at Sport-Thieme, I thought he'd be good for something. A carriage was already in the delivery of massive shortcomings (splintered wood, sharp, stiff metal parts, poor workmanship). Both slides were despite correct use (to avoid hardship, slow ride with two children aged 1 and 3 years, correct Aubewahrung etc.) after the 2-3 trip broken (wood splintered, already worn out hinges - risk of injury, etc.). Slides are no longer usable, some wooden parts would break in the next trips. Absolute full scrap! Do not buy.
