Best of many I've used. *by W***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on August 24, 2010* This Waterloo adjustable keyboard and mouse tray is the best of many I've used. There's no single dominant feature that stands out, but it's the best combination of many smaller features done well that make it my first choice overall -- by a signicant margin.-- Easy to install-- Easy to adjust -- slides in and out, swings left and right, tilts, adjusts up and down-- Low profile -- I'm tall and it will sit comfortably above my knees and still simply slide back under the desk surface without re-adjusting everything. It also doesn't have large hanging components on which to bang your knees (what it does have hanging is well behind the keyboard and out of the way of knees).-- Large keyboard surface has plenty of room for other things behind and beside the keyboard (pen, Post-It pad, etc.)-- Large hard mouse surface-- No glued on foam mouse surface to wear out, get grimy, and be impossible to remove/replace. I simply drop a regular, replaceable, surface (the thin Wow!Pad is my favorite for an optical mouse) atop the slide-out surface.-- Mouse is at the same height as the keyboard-- Mouse tray slides left or right for left-/right-handers or simply for a change of hands-- No built-in wrist pad. They promote poor wrist posture, abrade my wrists slightly, get grimy, etc. However, Waterloo does have an optional one you can add.I do have one complaint:-- The mouse tray slides very easily. I recommend putting a screw through the hole in the bottom to lock the mouse tray in place, or simply wedge it (a ladies foam wedge cosmetic applicator works great). ### ⭐⭐⭐⭐⭐ Very happy *by B***K on Reviewed in the United States πŸ‡ΊπŸ‡Έ on December 16, 2012* We have been using this product now for about a month and really happy with it. With both my wife and I being of very different body sizes we needed a keyboard tray that could be flexible. This one works great! For those people also looking to use it with a Microsoft Natural Ergonomic Keyboard 4000 I'm very pleased to let you know that it works just fine. While it doesn't exactly fit the tray is sits on it without rocking even with the keyboard's front riser installed. The only issue with using the riser is if you want to slide the tray under the desk you will need to make sure the tray is angled down just a bit.The product seems well built although I do wonder about the adjustment handle being plastic. While it isn't flimsy it is plastic and gets used several times a day. Other than that minor concern I expect everything to last a long time. ### ⭐⭐⭐⭐⭐ terrific keyboard tray *by D***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 8, 2012* A colleague just came into my office to check out my keyboard tray, which made me realize what a terrific item it was and that I should share my experience.Although the instructions are pretty weak, a few minutes looking at everything made it easy to install the tray. It went up solidly and stayed that way until we moved. It was removed by someone else for me (while I was away), but simple to reinstall in the new office. I have to note that a plastic piece broke off in the unskilled removal, so I have to be more careful now when I adjust the height.The tray is solid, adjustable, and tucks away nicely.I am very happy with this purchase. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/10498979-waterloo-premium-arm-keyboard-tray-and-mouse-tray-package-black](https://www.desertcart.tw/products/10498979-waterloo-premium-arm-keyboard-tray-and-mouse-tray-package-black) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-23*
