The category is loud, and most of the noise is unhelpful. Product listings compete on feature counts, and feature counts are close to meaningless. Choosing well is mostly a process of narrowing — deciding what you don't need, and paying attention to the few things that genuinely differ.
Start with external or internal
This is the only decision that really shapes the shortlist, and it's worth being honest with yourself rather than buying what seems most versatile.
External products sit against the skin — wands, bullets, and most air-pulse designs. They tend to be the easier starting point because there's less to think about and nothing to insert.
Internal products are inserted, and are usually shaped with some curve. Some do both at once. Those combination designs look efficient but depend heavily on whether the proportions happen to suit your body, which you can't know in advance. A first purchase is a poor place to gamble on fit.
If you're unsure, external is the lower-risk answer.
Power matters more than settings
A product advertising twenty vibration patterns is telling you almost nothing. In practice most people find one or two settings they return to and never touch the rest. Patterns are cheap to add in firmware, which is exactly why every listing has so many.
What actually differs is the motor. A strong motor with three speeds is more useful than a weak one with twenty patterns, and a weak motor is the most common regret with cheap purchases — not because it fails, but because it's underwhelming and gets abandoned.
Motor quality is hard to assess from a listing. Rough proxies: weight, battery capacity, and whether the manufacturer talks about the motor at all. A brand that has spent money on the motor tends to mention it.
Also consider noise, which correlates loosely with power and matters a great deal in a flat with thin walls. "Whisper quiet" is marketing language; look for a decibel figure or reviews that address it directly.
Material is a short list
Body-safe silicone is the default answer for a first purchase. Non-porous, properly cleanable, durable, and it doesn't degrade in normal use.
TPE is legitimate and common, particularly for sleeves, but it's porous — it can't be fully sterilised and has a finite lifespan. That's a reasonable trade for the right product, but it's a thing to know rather than discover.
What to avoid is anything that won't name its material. "Body-safe material" with no further detail usually means PVC or jelly, which contain phthalates and are the reason the category had a reputation problem for years.
Rechargeable, essentially always
Battery-powered products are cheaper up front and worse in every other respect: weaker output, output that fades as the battery drains, and a compartment that compromises water sealing.
Rechargeable is the standard now and the price gap has largely closed. Magnetic charging is preferable to a port with a rubber cover — covers perish and are the thing most likely to fail first.
Read the water rating, not the word
"Waterproof" is not a defined term. The IP rating is, and it's the difference between something you can rinse under a tap and something you can take in the bath.
For a first purchase, anything rated IPX6 or above is easy to live with, because cleaning becomes straightforward rather than careful. Below that, or with no rating published, cleaning means wiping and you'll need to be more deliberate about it.
Size: smaller than you think
First purchases skew large, and it's the most common source of a product going unused. Insertable products in particular are usually better at a modest size — the difference between comfortable and not is small, and there's no way to make something smaller after the fact.
Check the insertable length specifically, not the total length. The two are often quite different and listings aren't always clear about which they're quoting.
Where the price actually goes
Below about £30, something has been compromised — usually the motor, sometimes the material, often both. That doesn't make it unusable, but it's the range where disappointment concentrates.
Between £50 and £100 you're paying for a decent motor, verified silicone, a real water rating, and a warranty that means something. This is where most well-made products sit.
Above that, you're largely paying for design, brand, and occasionally genuinely novel technology. Diminishing returns, though not nothing.
The warranty is worth weighing more than people do. It's the clearest signal a manufacturer will give you about expected lifespan, because it's the only claim that costs them money if wrong. A twelve-month warranty and a twenty-four-month warranty on similar products tell you something the spec sheets don't.
Two starting points
A wand is the most forgiving first external product. Broad contact area, strong motor, nothing to position precisely, and useful for muscle tension as well — which also makes it the easiest thing to have sitting in a drawer.
For an internal product, warmth is a genuine addition rather than a feature-count filler. Heat helps with comfort and relaxation, which matters most when you're new to something.
Lubricant, briefly
Water-based is the right default. It's compatible with every material including TPE and silicone, and it washes off with water.
Silicone lubricant lasts longer and doesn't dry out, but degrades silicone products and shouldn't be used with them. Oil-based has no place here at all — it degrades latex and is difficult to clean out of porous materials.
If you buy one thing alongside a first purchase, make it water-based lubricant. It improves the experience of nearly every product in the category and prevents most of the discomfort people attribute to the product itself.
The honest summary
Body-safe silicone, rechargeable, a published IP rating, a real warranty, smaller than your instinct suggests, and fewer settings than the listing three price points down. That covers nearly everything that matters.
The rest is preference, and preference is something you find out by using something rather than by reading about it.
