I have used Blum Blumotion, Grass DynaPro, Salice Futura and Hettich Quadro slides. The Blum, Grass and Hettich slides get daily use in my own home.
I have very limited experience with the Salice slides, as they did not work with my frameless system. I will be ordering a sample set soon to re-visit them as I have made an adjustment to the system and they are now a viable option. The problem was that the side of the slide, that attaches the cabinet side, was about 5mm taller than everyone else’s and it conflicted with the bottom of the cabinet, if there was a drawer at that location (using 5mm system holes in a manual shop). Availability is solid for me through two strong sources.
I stopped using the Blumotion slides after a few years because of availability problems and poor suppliers, but they seemed to be a very good slide. I have some in my house and the soft-close has partially failed on one drawer, but I think the cabinet is around 10 years old so I am not complaining. The slide otherwise functions correctly.
Grass DynaPros…sigh… it’s been a love/hate relationship for years. I really love these slides when you can get them installed in a cabinet. They function awesomely and can be used in wide drawers without concern, but getting them shipped to me without damage proved to be challenging. In my opinion, the things that make these slides awesome are also there greatest weakness…too many fragile plastic/nylon parts. When the slides first started shipping they came separated (lefts and rights) by thick corrugated cardboard and I can’t recall having any problems with damage. However, I hated it because if you needed less than a full box, separating the slides out was a pain as the cardboard did a good job of locking the slides into position. Shortly after, Grass started nesting the slides together without any cardboard. I was initially happy, as grabbing a pair of slides was greatly simplified however, soon after, damage started showing up. At first, it was only a slide every now and then, maybe one in every 15-20 pairs, but then it started getting worse, recently to the tune of 20-40%. Broken bearing races, roller bearings sheared in half, rack-n-pinion gear that has jumped a couple of teeth, the front plastic thingie…all fragile plastic parts that do not survive rough handling. I heard many times that “this is the first they are hearing about any issues,” until I spoke to the counter people at another major supplier who admitted that they have a whole skid collecting damaged slides and that, as I suspected, the packaging in their opinion was to blame. Availability was great through multiple suppliers.
Currently I am using Hettich Quadro slides and am pleased. I’ve had one bad one in about 100. It worked fine but made a weird clicking sound when you slid the drawer closed. The problem is, I have to get them from a single non-preferred supplier, but it is a small price to pay for a good, reliable slide that can survive shipping from one of the big hardware suppliers. If I continue to use these I will have to find some additional reliable sources.
I hope this helps.
