The Stroke Score method
The Stroke Score is a 100-point score for automatic strokers, built entirely from specifications the manufacturer publishes. It is not a laboratory measurement, we do not claim one, and every point on every product page carries the sentence that justifies it.

What this score is, and what it is not
Almost every site in this category tells you it tested a machine for four weeks and measured it at some precise decibel level. Check the manufacturer's own page and that decibel figure is not there — it was invented, and so, usually, were the testing hours. That is a problem for you as a buyer and a legal problem for whoever published it.
AutoStrokerLab took the opposite route. We score only what a manufacturer publishes, we show the arithmetic, and we name the source of every number. You can recompute any score on this site yourself from the rules below. That is the whole product: not a claim to have felt more machines than anyone else, but a standard that stays identical across every machine and can be audited by anyone who cares to.
We have never accepted payment for placement, a ranking position or a score. We earn affiliate commission when a reader buys through our links, disclosed at the top of every page that carries one, and the weights below were fixed before any product was scored.
The six axes
| Axis | Points | Scoring rule |
|---|---|---|
| Max strokes per minute | 25 | 25 × (published maximum strokes per minute ÷ 300), rounded to the nearest point. A product with no published stroke-rate figure scores 0, and so does a product with no stroking motion. |
| Stroke length control | 20 | 20 points when the maker publishes more than one selectable stroke length, 10 for a single published fixed length, 0 when nothing is published or the product does not stroke. |
| Hands-free operation | 15 | 15 points when the product runs without being held — a thrusting machine, or a published stand that holds it. 0 for a handheld device with no published stand. |
| App & interactive sync | 20 | 12 points for published app control, plus 8 points for published interactive or video synchronisation. Both halves need to appear in the maker's own specifications. |
| Sleeve compatibility & care | 10 | 10 points for published compatibility with a broad sleeve range plus a sleeve designed to be removed and rinsed; 8 for a proprietary but removable and washable sleeve; lower if cleaning is not addressed at all. |
| Warranty & price | 10 | Price relative to the other products scored here: the cheapest capable product in the set earns the most, the most expensive the least, all else equal. Published warranty terms would count on this axis too, but none of the makers publish any in the specs we cite, so it is currently scored on price alone. |
| Total | 100 | The sum of the six axes above. Nothing is added, curved or adjusted afterwards. |
Why these weights
Forty of the hundred points sit on stroke rate and stroke-length control, because those two figures are what separates an automatic stroker from a sleeve you move yourself. Fifteen more go to hands-free operation for the same reason. That is deliberate and it has a visible consequence: excellent products that do not stroke score badly here. The Lovense Max 2 scores 29 out of 100 and the Lovense Gush 2 Motion scores 44, not because they are bad, but because this score measures one specific thing and says so.
Twenty points go to app control and interactive sync, which is the single biggest functional divide in the category — two of the six products we score publish it and the other four do not. The last twenty are split between sleeve compatibility and care, which quietly decides your cost over the following two years, and warranty plus price, which stops a score rewarding expensive hardware for being expensive. In practice no maker here publishes warranty terms, so that axis currently runs on price alone and we say so wherever it appears.
Noise: the axis that does not exist
There is no noise axis in the Stroke Score, and that is a decision rather than an oversight. No manufacturer of any machine we score publishes a decibel figure, so a noise rating could only come from us measuring it, and we do not have the equipment or the controlled room a real measurement needs. Instead, every product records a noise class of "not published", which is exactly what the evidence supports. Our quietest automatic stroker guide explains what you can infer from published design in the meantime.
How a score is calculated, worked through
Take the Lovense Solace Pro. Lovense publishes a 300 strokes-per-minute maximum, so the stroke-rate axis pays 25 × (300 ÷ 300) = 25 points. It publishes four selectable stroke lengths, which is more than one, so stroke-length control pays the full 20. It is a self-thrusting machine, so hands-free pays 15. It publishes app control (12) and interactive video sync (8), so that axis pays 20. Its sleeve is removable and washable but proprietary, which is 8 of 10. At $199.00 it is the most expensive product in the set and its warranty terms are not published, which is 7 of 10. Total: 95.
Now take the Fleshlight Universal Launch. No published stroke rate, so 0 of 25. Adjustable stroke, speed and position, so 20 of 20. A powered machine, so 15 of 15. No app at all, so 0 of 20. The broadest published sleeve compatibility of anything here, so the only 10 of 10 we award. $199.95 with no published warranty terms and no published speed figure to justify it, so 6 of 10. Total: 51. Two of those numbers are zeroes from different causes, and the product page says which is which.
What is scored, and what is not
We score 6 products: four machines and two hands-free devices that people land on while shopping for machines. Other automatic strokers exist — the Kiiroo Keon, The Handy and the Autoblow AI come up constantly in the same searches — and they are not part of these rankings. When they appear on this site it is as reference points in a sentence, never as a scored product or a recommendation.
Corrections
If a number on this site does not match the manufacturer's current published specification, the manufacturer is right and we are wrong. Every page carries the date its specs were last read so you can see how stale a figure might be, and prices on official stores move faster than anything else here. Always check the live product page before you buy.
Frequently asked questions
Does AutoStrokerLab test products in a laboratory?
No, and we say so on every page rather than in a disclaimer at the bottom. The Stroke Score is built entirely from specifications the manufacturer publishes on its own product page. We do not run a sound lab, a durability rig or a timed measurement setup, and we do not claim first-person testing hours we have not spent.
Why score products on published specs instead of testing them?
Because a score you can check is worth more than a score you have to trust. Every point in the Stroke Score traces back to a figure on the manufacturer's own page, so you can verify any number on this site in under a minute. Most competing sites publish invented decibel readings and unverifiable four-week test claims; a sourced number beats an unsourced one.
What does a zero on an axis mean?
One of two things, and the product page always says which. Either the manufacturer publishes no figure we can cite — for example Fleshlight publishes no maximum stroke rate for the Universal Launch — or the product is not built to do that at all, such as the handheld Lovense Max 2 on the hands-free axis. A zero is never the result of a test, because we do not run tests.
Does affiliate commission affect the Stroke Score?
No. The axes and weights are fixed before any product is scored and are identical for every product, and the arithmetic is published on this page so anyone can recompute a score themselves. We earn affiliate commission on purchases through our links, which is disclosed at the top of every page that carries one.
How often are the scores updated?
Whenever a manufacturer changes a published specification or a price. Every page carries the date the specs behind it were last read, and the comparison tables carry it too. If a maker publishes a noise figure for any machine on this site, that column stops reading "not published" the same week.
