What you need before you start

A clean, flat right side on your mouse and a few minutes to read the product page cover the basics. Ultralight mice are light by design, so any support you add changes how the mouse feels. Decide how much extra weight you will accept before you search. A grip that weighs 3 g, 5 g or 6 g is a different feel from one that is heavier, and the numbers matter more on a light mouse than on a heavy one. [1]

Decide what you want from the support before you search. A pinky rest gives your pinky a place to land instead of hovering or pressing the desk. If you want something you can move between two mice, say so in your search, since some supports are made for one specific mouse. [1]

Have a short list of questions ready:

Keep a note of the answers. Comparing the notes makes it easier to judge two supports side by side without having to repeat the same checks.

Step by step

These steps work for any support you add to an ultralight mouse.

  1. Check your mouse's right side. Look for a flat area where a rest can sit. A mouse with a rounded or curved right side may not hold a flat dock well. Reaper Mods says its rest fits most mice with a flat right side. [1]
  2. Read the product page before you buy. Look for the fit line, the weight of each grip and the price. Skip pages that do not say what the support is or how it attaches.
  3. Confirm the weight you are adding. Ultralight mice are light by design, so a support that adds a few grams changes the feel. Check the published weight of the grip you will use. [1]
  4. Check the hand it is made for. A support made for the right side of a mouse is not for left-handed mice. The Reaper Mods pinky rest is not for left-handed mice. [1]
  5. Clean the area where the dock will sit. A clean, dry surface helps the dock hold. If the dock uses an adhesive, read the page for how to remove it later.
  6. Attach the dock. Follow the product's instructions. If the dock uses a strong adhesive, the page should say how to take it off without leaving residue. Reaper Mods says the dock comes off hard plastic clean if you warm it with a hair dryer for a few seconds, then peel slowly. [1]
  7. Snap on the grip that fits your hand. Try each size if the kit includes more than one. The grips snap on and off with magnets, no tools. [1]
  8. Play a short session. Use the mouse for a few minutes and notice whether the pinky lands where you want it. If the feel is off, swap the grip size or move the dock a little.
  9. Decide after one session. If the support feels right and the weight is acceptable, keep it. If not, take it off and try the next option on your list.

Tools that can do it

The Reaper Mods Pinky Rest is one option for adding a place for your pinky to rest on an ultralight mouse. For other supports, use the checks above rather than relying on a claim you cannot verify.

Other supports. Any other support you find can be judged with the same list: fit for your mouse's right side, published weight, how it attaches, and whether it is for right-handed mice. Check each point on its own page, and write down what the page actually says.

Common mistakes to avoid

Adding weight without checking the number. Ultralight mice are light by design. Read the published weight of the grip before you buy, since a few grams matter more on a light mouse than on a heavy one. [1]

Assuming a support fits your mouse. Check the fit line on the product page. Reaper Mods says its rest fits most mice with a flat right side. [1] If your mouse's right side is rounded, check whether the dock will sit flat.

Buying a support for the wrong hand. A support made for the right side of a mouse is not for left-handed mice. [1] Check the hand before you order.

Skipping the removal instructions. If the dock uses an adhesive, read how to take it off before you attach it. Reaper Mods says the dock comes off hard plastic clean if you warm it with a hair dryer for a few seconds, then peel slowly. [1]

Judging the feel from the first minute. A new support changes where your pinky lands. Give it a short session before you decide.

Trusting a claim you cannot see on the page. If a product page does not say a feature exists, check it on the page instead of assuming.
