Went with these over Blume as they were a fraction of the price. The clips seem pretty cheaply made and are very difficult to make any meaningful adjustments. Would probably spend the $ on quality next time around.

I ordered the 6 pack of 21” slides. They worked very well. I had one plastic piece break and the company sent me an envelope with a replacement and did so without me asking. It was their decision. Very impressive.

Excellent quality. Superior to the sliders I replaced on by kitchen drawer. Straight forward and easy install. I plan to change out all my sliders using this brand (in time).

The sturdiness and ease of the connection for these bright, warm white (3000K) lights to become extended was why I went with this product over others that are currently advertised. You get 6 12" long LED (= money saved vs our old halogen) for a great price.The look is professional (see photo) and in the kitchen this means huge savings for a fraction of what a designer would charge. I ended up buying a second transformer for one of the segments to use elsewhere.Very happy.

As I've been building my cabinets and drawers I've found that these type sliders are the best for alignment for the drawers to guide in and out. The side mounted slides require exact sides or equal measurements. These under mounted sliders can be used with an optional end bracket, or screwed into the sides of the cabinet, if the sides are of equal distance apart from each other, which is what I did for my install. They glide so easy, and soft close, too. The three way adjustment clips are so easy to use, I wish all sliders came with them. Easy to build my drawers based on these slider parameters.

I recently used these Full Extension Concealed Undermount Drawer Slides as part of my home organization revolution. They've completely transformed my storage spaces, offering smooth and full drawer extension that makes accessing items a breeze. The concealed design keeps things looking sleek and tidy, and the installation process was straightforward.

I didn't want to buy an entire new kit when all I needed was the brackets, and these are perfect. I had previously bought some to replace mine that broke, but once I opened that other package, I could see the poor quality of the other ones. I took those back to H. D. and ordered these higher quality ones on Amazon. These are a much better quality and just what I needed!

I've installed a lot of drawer slides. Undermount slides are a bit more complicated to install and adjust then the standard side mount slides. The drawer has to be specifically constructed for undermount slides. Some of this type of slides come with adjustment features built into the attachment device. Not all slides adjust in every direction - in/out, right/left, up/down. And some adjust easier than others.These slides arrived very well packaged. Nothing was damaged. I have ordered other brands from cabinet builders supply houses, and many were damaged. They were not packaged as well as these were. These are heavy steel construction. They slide smoothly and have soft close feature built in. The adjustment head that mounts at the front bottom side of the drawer has a full set of adjustments so you can get an exact fit. I have included a picture of a Blum brand mount I installed recently so you can compare the construction of the adjustment head to these. The particular Blum did not have all the adjustments, but you can see the construction differences. These slides adjustments are a lighter weight construction so I don't know how well they will hold up with time, but once adjusted you will probably never touch them again. For the price, these are a very good set of drawer slides.

These full extension slides attach to the bottom of the cabinet drawer allowing the drawer to be constructed at the maximum width possible. Of course the trade off is that it consumes some of the drawer’s inner height.The slides mount to the inside walls of the cabinet - or if there is a front frame reducing the width, it can be mounted on an optional rear wall bracket and the edge of the front frame.These bottom mount drawer slides are easily adjustable by means of 3 red knobs in the attachment assembly moving it up/down, left/right, or in/out.Most impressive is the smooth auto closing function which draws the drawer gently and quietly in the last 2 inches to its closed position.
