How to Read a Spec Sheet: Decoding Marketing Claims
How to decode a product spec sheet - motor type claims, runtime claims, IP ratings, material nomenclature, 'medical grade' language, and which specs are marketing noise.
A spec sheet is where a product either proves itself or hides. Vendors lead with adjectives - “rumbly,” “medical grade,” “whisper quiet” - and bury or omit the numbers that would let you check those adjectives. This guide gives you a field method: for each common claim, what a real number looks like, and when the claim is noise.
Motor type claims
“Rumbly” and “buzzy” describe frequency. Low-frequency vibration reads as deep and travels through tissue; high-frequency reads as surface buzz. The problem is that every vendor calls its motor rumbly.
What to look for: a stated frequency in Hz, or a measured noise band at a distance and setting. If the listing gives neither, assume the motor is average. The motor types guide explains the frequency split in plain terms. The We-Vibe Tango X is a compact example where a low-frequency profile is the actual selling point, not just a word.
Runtime claims
Every runtime number is missing a setting. “Up to 2 hours” almost always means the lowest intensity. At max, that same battery may give 40 minutes. A honest spec states runtime per setting or at max.
| Claim as written | What it usually means | What you should want |
|---|---|---|
| ”Up to 2 hours” | 2 hours at lowest setting | Runtime at max setting stated |
| ”All-day standby” | Irrelevant to use | Continuous-use time |
| ”Fast charge” | Vague | Charge time to 80 percent, in minutes |
The Magic Wand Rechargeable states a runtime that, like all wands, is short relative to bullets because the motor draws far more power. That trade is real and worth knowing before you buy a wand expecting all-day use.
IP ratings
IP ratings are a real standard, and the number after IPX is the claim:
- IPX4: splash resistant. Wipe, do not rinse under a tap.
- IPX6: strong jet, can be rinsed.
- IPX7: immersion up to 1 meter for 30 minutes. Fully washable and bath-safe.
No number means no tested water resistance - assume none. The waterproof IP ratings guide walks the scale. Note that IPX says nothing about sound or material; it is one axis only.
Material nomenclature
Material names are where vendors blur. Watch for:
- “Silicone” with no qualifier on a cheap flexible product. True silicone over a non-porous core is safe; a “silicone blend” or “silky coat over TPE” is usually porous underneath.
- “Body-safe” with no material named. Body-safe is a claim, not a substance.
- “Hypoallergenic” with no stated composition.
A trustworthy listing names the actual material: platinum-cure silicone, ABS, borosilicate glass, 316L steel. The toy material comparison maps each to its safety profile. The silicone grade guide explains why platinum cure matters.
”Medical grade” language
“Medical-grade silicone” is the most abused phrase in the category. Real medical-grade silicone is a defined class of platinum-cure material used in implants and devices, and a reputable maker can name the standard (for example ISO 10993 or USP Class VI) on request. If the listing uses “medical grade” as a mood rather than a cited spec, treat it as marketing.
The distinction matters: a product can be body-safe silicone without being medical-grade, and “medical grade” without a named standard proves nothing. Ask for the certification; absence of an answer is the answer.
Charging port and connector type
Charging is where a spec sheet hides future frustration. Two connector styles dominate: magnetic and pin. Magnetic charging snaps into place with no exposed port, which lets the whole body be sealed and waterproof; it is the better design for longevity and for users with limited hand strength. Pin or barrel connectors require a small cap that must be opened and closed, and the seam is a common failure and moisture-ingress point. A listing that says “USB rechargeable” without naming the connector type is omitting the detail that predicts whether the device stays usable in a year. The charging care guide covers cycle life and what “fast charge” usually means in practice.
Which specs are marketing noise
Some listed “features” carry no usable information:
- Number of modes or patterns, stated alone. Ten patterns mean nothing if the lowest intensity is still too strong.
- “USB rechargeable” with no charge time or port type. Magnetic beats pin connectors for waterproofing.
- “Travel lock” claimed but not described; some batches omit it.
- “Powerful” with no dB or frequency. Power without a noise figure is a privacy risk, not a benefit.
Who should ignore the spec sheet entirely
If you have a diagnosed condition affecting tissue, nerves, or pelvic health, spec-sheet shopping does not replace clinical guidance. This guide is educational. A clinician can advise what intensity, material, and form are appropriate for you. The accessibility pillar and chronic illness pillar cover accommodation-first paths.
Practical protocol
- Find the material name. If it is not a real substance, stop.
- Find the noise figure. If none, assume loud and weigh that against your home.
- Find runtime at max setting, not “up to.”
- Confirm the IPX number and match it to how you will clean.
- Treat “medical grade” as unproven unless a standard is named.
- Ignore mode counts and “powerful” unless backed by a number.
- Cross-check the vendor’s claims against owner reports before buying.

Common questions
What spec matters most for a first product?
Material, then noise, then charging type. Material decides whether it is safe to keep; noise decides whether you will actually use it in your home; magnetic charging decides whether it stays usable over time.
Is a higher IPX number always better?
For cleaning, yes - a higher number means more water exposure is allowed. But IPX ratings say nothing about noise, battery, or material. Treat them as one axis, not a quality score.
