How I Test
Every score on this site traces back to the protocol on this page. Same kit, same steps, same math, every product.
Most reviews in this niche are written by people who never touched the product. You can tell — they read like the manufacturer's page with adjectives added.
This page exists so you can check my work. If a review says a sleeve takes six hours to dry, it's because I put it on a rack and checked the clock — not because I guessed.
Who's testing
I'm Spencer Harter. I spent 8 years at Fleshlight as a product specialist, and I now run this site independently. I'm also the founder of Beat Bagz, a disposable alternative that will compete with some of the products I review. And I earn affiliate commissions on many of the links here — including Fleshlight's.
That's three conflicts of interest, disclosed up front, because you deserve to weigh them. Here's how I keep them from mattering: everything on this site comes from my own testing or from a public source you can verify yourself — a label, a patent filing, a review page, a forum thread. I don't publish internal company information, I don't take paid placements, and when a product I compete with is the better buy for you, I say so. Tenga has earned plenty of recommendations on this site. That won't change.
The kit
Nothing exotic — about $100 of gear, so you could re-run any of this at home: a digital kitchen scale (lube used per session, to 0.1 g), a stopwatch (active cleaning time, every step from sink to rack), a hygrometer (room conditions during every drying test, because "it dries overnight" means nothing without knowing the humidity), an infrared thermometer (warming tests), calipers (orifice and canal measurements), and a labeled drying rack — every sleeve dries in the same spot with the same airflow.
The Cleanup Score
The number this site is built on. After every test session I clean the toy exactly per manufacturer instructions, timed, then dry it on the rack and log hours until bone-dry — checked by touch at the deepest chamber. Conditions are stated in every review.
| SCORE | LABEL | WHAT IT MEANS |
|---|---|---|
| 5 | Rinse & done | Under 2 min of care, no drying wait. Disposables live here. |
| 4 | Easy | Under 5 min active, dry in under an hour. |
| 3 | Manageable | 5–10 min active, 1–4 hours drying. |
| 2 | Committed | 10–15 min active, 4–8 hours drying, texture traps that need finger-work. |
| 1 | High-maintenance | 15+ min, 8+ hours drying, disassembly or special products required. |
The other protocols
Cost per use. Price ÷ realistic uses. For reusables: (price + a year of lube and care supplies) ÷ (2 uses/week × 52). For disposables: unit price + lube, flat. The formula is shown in every review so you can plug in your own numbers.
Texture mapping. Every reviewed sleeve gets a measured cross-section diagram. The sleeve comes out of its case, gets photographed on the bench against a ruler, and I read the chamber boundaries off the photo to the tenth of an inch. The diagram you see is drawn from those measurements — my sleeve, my ruler, my numbers. For products not yet on my bench, early diagrams are drawn from the manufacturer's published, ruler-measured imagery and labeled as such until I've verified them on a unit I own.
Durability log. Test products stay in rotation. I log condition at 10, 25, and 50 uses — tears, texture wear, smell, discoloration — and update the review. A review here is a living document; the "last updated" date is real.
Feel. Sensation is subjective and I label it as such. What I can do is describe why something feels the way it does — texture geometry, tightness, suction — so you can map my experience onto your preferences instead of taking my word for "amazing."
What I don't do
No paid placements. No scores for products I haven't handled — if I'm analyzing something from public specs and texture diagrams only, the article says so and there's no score. No free review units without a disclosure line. No internal company information from my time in the industry — my old job opens doors of understanding, not filing cabinets.
The verdicts
Buy — I'd spend my own money on it, and did. Conditional — right for a specific person I'll describe exactly. Skip — the money is better spent elsewhere, and I'll tell you where.
Questions about the method? If you can think of a test I should be running, I probably want to run it.
