Why "quality" matters
A magnetic holder isn’t just a look upgrade - it’s a part you trust every day at speed, in rain, and in car-washes. After 500+ orders, we’ve learned what truly separates a great holder from a cheap one. Below is your buyer’s guide plus how SleemPlate checks every box.
1) Retention engineering (the core)
-
Magnet–magnet architecture at two lateral points → four magnets per plate for balanced load sharing.
-
Extreme Performance: up to ~18 kg per plate (ideal lab conditions); a front+rear set markets ~36 kg combined. Real-world retention depends on flatness, alignment, vibration - which we optimize in the design.
-
Screw-mounted pucks (no adhesives), clean look, repeatable placement.
2) Materials that last (and look premium)
-
Neodymium N52 magnets, Zinc plated + black epoxy anti-corrosion - a distinct SleemPlate look that also protects against salt and moisture.
-
Magnet size: Ø20 mm, thickness 5 mm (holder) & 4 mm (puck).
-
Operating range: −30 °C…+60 °C.
-
No adhesives; IPA wipes included for proper surface prep.
3) Fit & geometry, done right
-
Target format: EU 520×110 mm.
-
MagSleem X: compatible with any plate size worldwide.
-
Honeycomb (Audi-style): puck Ø28.4 mm (extendable to 40.2 mm). Blocks 36 mm tip-to-tip (recommend ≤32 mm cell height without extender; up to 40 mm with extender, ≤36 mm recommended).
-
Works on aluminum/plastic/steel bumpers (magnet–magnet via screws). No issues observed with ACC/radar/parking cameras.
4) Installation experience you won’t dread
-
Five clear steps, one cross-head screwdriver, no washers, no glue.
-
Reversible and tidy. IPA wipes included so you start with a clean surface.
5) Real-world reliability (speed & wash)
-
Validated in Autobahn usage, off-road and track scenarios.
-
Car-wash tip: jet ≥30–40 cm at an oblique angle; avoid blasting under edges. (Internal tests OK down to ~20 cm, but keep a margin.)
6) Legal alignment (principles, not loopholes)
Correctly installed, the system follows the legal principles: plates in the designated front & rear positions, clearly visible; the method isn’t specified. Outside EU/RO, always check local rules.
7) Aftersales you can actually reach
-
WhatsApp support <5 minutes during business hours (and ~1 hour for urgent after-hours within reasonable times), plus phone and email.
-
Warranty: 2-year EU (and where required), 1-year elsewhere.
-
Returns: 14-day EU withdrawal + 90-day satisfaction return if intact.
-
Spare parts available, so you never throw away a full kit for one damaged piece.
Red flags when comparing brands
-
Glue-only or tape-only “solutions”.
-
Single-point magnet layouts or magnet-to-steel designs.
-
Shiny nickel magnets without epoxy (fast corrosion near the road).
-
No honeycomb guidance or extenders; vague fit claims.
-
No parts catalogue, no warranty specifics, no car-wash instructions.
-
No way to reach support quickly.

Quick FAQ
Do magnets interfere with sensors? No issues observed; don’t cover radar windows.
Aluminum/plastic bumpers? Yes - magnet–magnet via screw-mounted pucks.
Maintenance? None required; optional winter rinse.
Honeycomb grilles? Yes - blocks & extenders; see the honeycomb guide.
