Sprime PM1 Review
Introduction
The Sprime PM1 is the first mouse released by Sprime, featuring an ergonomic shape with a design that closely resembles the Logitech G703. With a cult following in the gaming community, the PM1 aims to capture the essence of the G703 while offering improved internals and a much lighter weight. It shares many similarities with the Ninjutso Sora V2, including materials and internals, but with notable differences in shape. In this review, we will dive into the mouse’s features, performance, and overall impressions.
Internals and Features
The Sprime PM1 is equipped with the popular PixArt 3395 sensor, known for its precision and performance. Weighing just 43.7 grams, the PM1 is one of the lightest gaming mice on the market, with an advertised weight of 43 grams. This makes it an attractive option for gamers looking for a lightweight, high-performance mouse.
The PM1 features a Nordic chipset and comes with Rron Optical switches, which are known for their responsiveness and reliability. However, the PM1 is advertised as 8K polling ready, but the required 8K dongle is not yet available. As a result, the mouse currently supports only 1K polling. This delay has been frustrating for many users, and it remains unclear when the 8K dongle will be released.
Despite the 1K polling limitation, the PM1 includes Prime Speed Wireless technology, similar to the Snappy Fire wireless found in the Sora V2. This feature helps improve performance despite the lower polling rate, though it comes at the cost of higher power consumption.
Shape and Grip
The Sprime PM1 features an ergonomic shape that closely resembles the Logitech G703, but it is slightly smaller in size. This makes it a viable option for various grip styles, depending on hand size. However, as a fingertip grip user, I found the shape somewhat uncomfortable. The left-click being positioned higher off the pad than the right-click felt awkward and unbalanced for my grip style.
While ergonomic shapes are generally preferred by many gamers, this particular design did not suit my personal preferences. I tend to favor symmetrical mice for better control and comfort.
Build Quality and Clicks
The Sprime PM1 features Rron Optical switches, which are some of my favorite switches due to their fast response time. However, the unit I tested had a slight squeaking issue with the clicks, which became quite noticeable during use. The material of the clicks is somewhat flimsy, which can lead to post-travel if your fingers extend to the end of the buttons. This issue may be particularly bothersome for users with a grip style that requires more precise clicks.
The side buttons also exhibit some post-travel, but they are not as noticeable during gameplay. The size and positioning of the side buttons are excellent, making them easy to access without feeling too awkward or cramped.
Coating and Skates
The coating on the PM1 is slightly more slippery compared to the Sora V2, which surprised me. The lighter weight of the mouse compensates for this somewhat, but if you prefer more grip, aftermarket grips are a good option. The PM1 does come with grips in the box, so you can add those for extra comfort and control if needed.
The stock skates on the PM1 are not great, and I quickly switched them out for Ghost Glide Edge Runners. This simple upgrade improved my experience significantly, and I highly recommend doing the same for optimal performance.
Performance
Despite the 1K polling rate, the performance of the Sprime PM1 in competitive mode is impressive. The mouse is very responsive, and the side buttons work well in games like Fortnite due to their positioning and size. I also recommend enabling competitive mode for better performance, even though it consumes more power.
Final Thoughts and Rating
After testing the Sprime PM1, I would give it a rating of 3.5 out of 5. While the mouse is lightweight and responsive, it didn’t wow me as much as other mice in its class. The clicks are not ideal, the coating is slippery, and the ergonomic shape did not complement my grip style.
For those seeking better build quality and a more refined experience, I would recommend looking at options like the Zowie U2 or the Vaxee R1 Pro. If you prefer a budget-friendly option, mice like the Zalin Z1 or Z2 are great alternatives.
Conclusion
The Sprime PM1 is a solid mouse, but it falls short in a few key areas. The ergonomic shape, while suitable for some users, did not work for me as a fingertip gripper. The delay in the 8K polling dongle and issues with the clicks are also points of concern. However, if you’re looking for a lightweight, high-performance mouse with a decent build quality, the PM1 may still be worth considering.
