These types of comments are typically of little value unless you are very familiar with the individual reviewer and are confident that you will share the same opinion.Type 2:
Subjective comments with comparisons (eg. "The mousefeet were worse on the Kana than on the Sensei. The Kana was not as comfortable as the Sensei.")
These types of comments are more useful because they allow an individual who is not familiar with the individual reviewer to determine whether or not they would share the same opinion. If the reviewer describes the mousefeet on the Sensei as "terrible" and also says that the mousefeet were "worse than the Kana", and I believe the mousefeet on the Kana are okay, then I will disagree with the reviewers subjective opinion.
Mousefeet (and mousepads) can be compared by their static coefficient of friction. While this could theoretically be calculated exactly, it is usually done by simply placing different mice on different mousepads, and comparing the angle at which the pad must be sloped before the mouse will slide. A steep angle means a slow mousepad or slow mousefeet, and a shallow angle means a fast mousepad or fast mousefeet.Type 3:
Objective comments (eg. "The Kana cursor will occasionally jump left when moved straight up or down. The Kana has some mild prediction.")
While in some cases you can argue about testing methods (combinations of mousepads, etc), generally speaking these types of comments are sufficiently objective that they will apply to any person who uses the mouse. These are typically specifically tested for using means other than normal use of a mouse (during which they may or may not be subjectively noticeable).
Prediction and Jitter are typically tested for by drawing various figures in MSPaint - straight lines, sloped lines, and spirals and circles. These can sometimes be more easily felt by the tester during the testing than observed by the reader of a review, but anyone who has used a number of mice can attest to their presence, and they can usually be easily observed in the results.Prediction
is evident when the mouse cursor has an unnatural tendancy to produce straight lines horizontally and vertically. Straight lines are very straight, sloped lines tend to have significant straight portions to them, and spirals and circles tend to be more square. The Kinzu V1 for example, has very strong prediction is noticeable in MSPaint tests. User-error is minimized by performing multiple tests, with multiple mice, and comparing the results.Jitter
is evident when the mouse cursor wiggles from side to side or up and down when moving the mouse smoothly in one direction. The Abyssus for example, tends to jitter in specific circumstances and that jitter is noticeable in MSPaint tests. User-error can be eliminated by placing the mouse against a straight surface (such as a book) and moving the mouse along the surface in a straight line while drawing in MSPaint.Acceleration
is evident when the mouse cursor moves more quickly when the mouse is moved faster (positive acceleration) or more slowly when the mouse is moved faster (negative acceleration). Acceleration is frequently tested by moving the mouse at different speeds in a 3D first-person game and checking whether the mouse cursor returns to the same location each time, although it could be tested in any mousing environment. User-error can be eliminated by placing the mouse against a straight surface (such as a book) and moving the mouse along the surface in a straight line to a definite stopping point to ensure that the physical distance moved is always the same.
is evident when the mouse cursor fails to move or moves erratically when the mouse is moved quickly. Similar to Acceleration testing, user-error can be minimized by moving the mouse along a straight surface to a definite stopping point. If the mouse cursor failed to reach the end point when moved quickly, either by abruptly stopping or other erratic movement, sensor malfunction has occurred. The exactly malfunction speed is typically tested by ENOTUS Mouse Test software, which, whether accurate or not in its specific results, provides a baseline for comparison between mice. If your current mouse shows a malfunction speed on ENOTUS of 1m/s, you can be confident that all other mice that test at 1/ms or higher will perform at least as well as your current mouse.LASTLY:
I would like to point out the difference between the types of reviews you would typically see on the OCN forums, versus the types of reviews you would typically see on other, perhaps more generic or mainstream, review sites.
Reviews on the OCN forums tend to hit each of the above types of comments, including a users subjective opinion of the mouse, a comparison versus other mice they own or have used, and objective testing data on sensor performance.
Reviews on other generic or mainstream review sites typically only hit the first type of comments, and are therefore largely useless. I believe this is because: (1) most reviewers do not know how to properly test a mouse, (2) most of these sites typically will not wish to uncover real hardware problems from a product they have received free from the manufacturer and asked to endorse, and (3) as evidence by this thread (and others), many users are simply oblivious to the more technical nuances that affect mouse usage.
At the end of the day, you simply buy what you think will make you happy. If you care about the objective sensor performance, look for reviews that deal with those issues. If you don't understand or simply don't care about technical sensor performance, buy whatever has the features and style you like. If a review says "this mouse is good" and doesn't explain why in a manner that you can relate to, it is a meaningless review which you should not rely on.
Given that you are on a very highly specialized forum with a large number of people very dedicated to their mice, the "tier lists" and comments you will see posted here usually are coming from people who have read a large number of reviews, and owned and tested a large number of mice. If you ask them WHICH mouse is best, they will give you their opinion. If you want to know WHY those mice are best, you can see their respective reviews which deal with all of the issues I've mentioned above, and decide for yourself which mouse fits your needs.
