90-Day Trial
Hearing protection is only worth owning if it performs where you actually use it — on the range, on site, in the workshop, at the stand. Which is why we don't ask you to judge ours after five minutes in a hallway.
Take your DEISTORM protection into the field. Use it properly, repeatedly, for a real season of sessions. If it doesn't do what we said it would, we'll refund what you paid for it.
This is a performance guarantee, not a 90-day loan. It exists for customers who bought the product, used it correctly and found it fell short. It is not a way to borrow equipment for a season. The conditions below are deliberately strict, and we apply them consistently to every claim.
What the trial covers
A refund of the product price if, after genuine and consistent real-world use, your DEISTORM product does not deliver the noise reduction, comfort or functionality described on its product page.
What the trial does not cover
- Change of mind, or deciding you'd prefer a different model — use your 14-day right to cancel instead
- Damage from drops, crushing, impact, water exposure beyond the product's stated rating, modification or use outside the supplied instructions
- Consumable wear items: ear pads, foam inserts, ear tips and batteries
- Products bought from third-party sellers, marketplaces or resellers
- Products bought at a discount of 30% or more, or as part of a clearance
- Lost or stolen products
Eligibility conditions
Every condition below must be met. A claim that fails any one of them will be declined.
1. Direct purchase
The product must have been bought directly from deistorm.com, in a single retail order, at full or standard promotional price.
2. Minimum use period — 60 days
The trial rewards real testing, not first impressions. You must have used the product on at least 10 separate occasions across a minimum of 60 days from the delivery date. Claims submitted before day 60 cannot be accepted under this trial.
3. Claim window — day 60 to day 90
Claims must be submitted between day 60 and day 90 inclusive, counted from the date your order was delivered. The window closes at the end of day 90. There are no extensions.
4. Evidence of consistent use
Your claim must include both of the following:
- A written usage account — where you used the product, how often, approximate dates, the conditions and noise levels involved, and a specific description of what did not perform and how.
- At least four clear, dated photographs of the product in its current condition, showing both cups or units, the headband or case, and the sealing surfaces.
Claims that are vague, unverifiable or inconsistent with the condition of the returned product will be declined.
5. Complete return — everything in the box
The product must come back with every component it was supplied with: the outer box, inner tray or foam, carry case or pouch, all ear pads and ear tips in all sizes supplied, charging cable, batteries, manual, warranty card and any spare parts.
If any component is missing, the claim will either be declined or the refund reduced by the retail value of the missing items. Keep your packaging for the full 90 days — without it, a trial claim cannot be completed.
6. Product intact and unmodified
The serial number or identification label must be present and legible. Products that have been opened, modified, repaired by a third party, or had identifying marks removed or defaced are not eligible.
7. One claim per customer
The trial may be used once per customer, household or delivery address. Making a successful trial claim ends eligibility for future trial claims on that account.
8. Returns authorisation required
Nothing may be sent back without an RMA number issued by us in advance. Unauthorised parcels are refused and returned at your cost.
How to make a claim
- Email us between day 60 and day 90 at SUPPORT@DEISTORM.COM with the subject line 90-Day Trial Claim – [your order number]. Attach your usage account and photographs.
- We review within 5 business days. We may ask follow-up questions about how the product was used — often we can solve a fit or setup issue on the spot, at no cost to you.
- If approved, we issue an RMA number and the return address. The RMA is valid for 14 days.
- You return the product, tracked and adequately packaged, at your own cost. The parcel remains your responsibility until it reaches us.
- We inspect within 5 business days of arrival against the conditions above.
- If the claim is upheld, the product price is refunded to your original payment method within 10 business days. The original delivery charge is not refunded.
The honest part
We fund this trial so you can buy without hesitating. In return we ask one thing: only claim if the product genuinely didn't perform for you.
Return postage is yours to cover and the original delivery charge is not refunded. That's deliberate. The trial is designed to protect you against a product that fails you — not against changing your mind. If you simply don't want the item, your 14-day cancellation right is faster, simpler and better suited to that.
Misuse of the trial
We reserve the right to decline a claim where the evidence provided is inconsistent, unverifiable or fabricated; where the product shows damage caused by misuse; or where an account shows a pattern of repeated returns or payment chargebacks. Claims found to be fraudulent will be refused and the account restricted from future trial eligibility.
Your statutory rights
This trial is a voluntary commercial guarantee offered in addition to your legal rights. It does not replace, reduce or limit your rights under the Consumer Rights Act 2015 or the Consumer Contracts Regulations 2013, including your 14-day right to cancel and your rights where goods are faulty or not as described. Those rights are set out in our Shipping & Returns policy.
This guarantee is governed by the law of Scotland.
