Globular Cluster GPQ3 Review: Better for Big Hands, but Build Quality Disappoints
The GPQ3 gives Quest 3 and 3S controllers 3 cm of extra grip, improving comfort in some games while creating new problems in others.

Quick verdict
The GPQ3 is one of the few controller grips made specifically for larger hands. Its extra 3 cm (1.2 inches) gives your fingers more room and allows several different holding positions. It works especially well in games such as Beat Saber and Eleven Table Tennis, where I do not need constant access to the trigger.
However, the added length becomes uncomfortable when I support a one-handed weapon with my second hand. My review units also had gaps and flexible sections that moved when squeezed. At $30, I expected better construction straight out of the box.
Pros
- More room for large hands and the pinky finger
- Several comfortable holding positions
- Particularly good for Beat Saber and Eleven Table Tennis
- Wide, soft and stretchy hand strap
- Cutout avoids covering a tracking LED
- Simple installation and quick removal
Cons
- Awkward when supporting a pistol with the second hand
- Oversized grip may not match virtual hands or weapons in mixed reality
- Gaps and flex between parts on my review units
- Tightening the screws did not solve the movement; glue was needed
- Strap attaches to plastic rather than metal
- Color and surface texture do not perfectly match the controller
- Limited benefit if your hands already fit the standard controller
Comfort and gameplay
My hand is about 9 cm wide and usually fits a large glove. The standard Quest 3 controller is already usable for me, although my pinky finger could use more space. The GPQ3 solves that problem and lets me hold the controller higher, lower or at different angles.
The extra length provides more freedom to change your grip.
This makes the GPQ3 more comfortable in games where the trigger is not important. It also worked well when using two pistols. The problem appeared when I held one pistol and supported it with my other hand: the extended grip pressed into that hand and quickly became uncomfortable. A regular controller works much better for this position.
The extra length can get in the way when supporting a one-handed weapon.
Because the physical controller is larger, it can also extend beyond the virtual hand, paddle or weapon shown in mixed reality. This is not unique to the GPQ3—it is a compromise of any oversized controller grip.
Strap and construction
The hand strap is one of the better parts of the GPQ3. It is wider and stretchier than many standard straps, stays comfortable during long sessions and leaves space for the controller’s tracking LED.
The strap is comfortable and does not obstruct the tracking LED.
The construction is less convincing. Both grips had visible gaps and sections that moved when squeezed, with the left grip being slightly worse. Tightening the internal screws did not fix it. Adding glue reduced movement in some sections, but one area still flexed.
My units had gaps and noticeable movement between components.
Glue helped, but it did not completely eliminate the flex.
I am also concerned that the strap is connected to a plastic section rather than metal, which could make it more vulnerable in a fall. The plastic is slightly darker than the Quest controller and has a different texture—not a major functional problem, but disappointing at this price.
Should you buy it?
The GPQ3 makes sense if your hands are genuinely too large for the standard Quest 3 or 3S controllers, or if you mainly play games that benefit from a longer, more flexible grip. I will continue using it for titles such as Eleven Table Tennis and Beat Saber.
For average-sized hands, it is a smaller comfort improvement rather than a game changer. The shooting-game limitation and build-quality problems make the $30 price difficult to justify. My conclusion: useful for the right person, but only just OK in its current form.
