Push open drawer slides look solid and well made. The metal construction is durable and the extensions open easily. Due to the oil-lubricated ball bearings, they get a bit dirty during installation, but can easily be cleaned with a damp cloth. I noticed this item because of its push-to-open function and its above-average resilience. The limiter is plastic so it will be interesting to see how it holds up in daily use. So far I have been satisfied and would recommend this drawer slide.
