Tiered warranty coverage and a disclosed return policy, alongside a real, official battery recall
Sublue (Sublue Technology Inc., with offices in Los Angeles, Amsterdam, Tianjin and Shenzhen) sells underwater scooters (Mix, MixPro, Navbow, Navbow+, VAPOR, VAPOR Pro, Swii), a robotic pool cleaner (BN/BN Pro) and accessories, sold direct and through retailers including Amazon and Costco.
Sublue offers a 30-day return on unopened, unused products in original packaging, with the refund reduced by payment-processing fees (starting at 2.5%) and, for non-USD orders, currency-conversion fees (starting at 1.5%); an opened-but-unused item instead loses a 10-50% restocking and refurbishment fee determined by inspection. Warranty coverage is specific and tiered by product: 12 months on most scooter components, 24 months on the VAPOR line's main unit and motor, and 36 months on the BN/BN Pro pool cleaner's non-consumable parts. The most important fact for any buyer to know is a real, official recall: on 13 March 2025, the U.S. Consumer Product Safety Commission (CPSC, recall #25-169) recalled black replacement batteries sold for Sublue Mix underwater scooters (arctic white, space blue and aqua blue units sold June 2018 through February 2025, about 40,370 units) due to a fire hazard, after 161 reports of thermal or swelling incidents including eight fires, one injury and over $651,000 in reported property damage. Sublue is offering a free gray replacement battery and publishes the recall on its own site. We have not purchased or used a Sublue scooter ourselves.
Right for
- Buyers specifically researching the Mix scooter who need to check whether their unit has a recalled black battery before use
- Shoppers comfortable with a tiered, product-specific warranty rather than one blanket term across the whole catalogue
- Buyers who will keep original packaging and return items unopened if there is any chance they will return
Wrong for
- Anyone who already owns, or is about to buy secondhand, a Sublue Mix scooter without first checking the battery color against the CPSC recall
- Buyers expecting a full refund on a returned order, since payment-processing and currency-conversion fees reduce the refund even on unopened returns
- Shoppers who open packaging to test the product before deciding whether to keep it, given the 10-50% restocking fee that applies once a box is opened
+What it gets right
- Sublue publishes its own CPSC recall notice directly in its site navigation rather than only through the CPSC database. A dedicated "Battery Recall" link appears in the Customer Care menu, which is a real transparency signal around a serious safety issue.
- The warranty is specific and broken down by product and component. Mix/MixPro/Navbow get 12 months across body, motion system and battery; VAPOR gets 24 months on its main unit and motor; the BN Pro pool cleaner gets 36 months on non-consumable parts.
- Sublue covers return shipping for approved quality-related claims, generally with a prepaid label. This is a specific, favorable detail for the one return scenario (a confirmed defect) buyers care about most.
- A 7-day price-protection policy is disclosed with specific, named exclusions. Clearance items, flash promotions, coupon discounts and bundles are explicitly excluded from price matching, so the terms are concrete rather than vague.
−Where it slips
- An official CPSC recall (#25-169, 13 March 2025) covers black batteries sold for Sublue Mix scooters from June 2018 through February 2025 due to a fire hazard. 161 incident reports, including eight fires and one injury, were recorded before the recall; any buyer of a used or older Mix unit needs to check the battery color before using it.
- Refunds on unopened returns are reduced by payment-processing (2.5%+) and currency-conversion (1.5%+) fees. Customer-reason returns are not fully refunded even when the product is unopened and unused.
- Opening the box, even without using the product, triggers a 10-50% restocking and refurbishment fee. The exact percentage is determined by Sublue's own inspection, which gives buyers little ability to estimate the fee in advance.
- A used product without a confirmed quality issue cannot be returned at all. Once a scooter has been used in water, remorse-based returns are not accepted regardless of condition.
- Non-U.S. return-shipping cost responsibility depends on "which party pays," worded ambiguously enough that it is worth confirming directly for a specific country. International buyers cannot determine their exact return-shipping cost exposure from the policy text alone.
Weighted for return-policy clarity, warranty specificity and the real safety-recall disclosure
This is a desk-research review: we have not used a Sublue scooter. The recalled Mix battery, confirmed directly via the CPSC's official notice, is the central fact buyers need; Sublue's own disclosure of it is a partial offset.
The long version
What Sublue sells, how its return and warranty terms actually work, the specifics of the official CPSC battery recall on Mix scooters, and what to check before buying or using one.
What Sublue sells
Sublue sells underwater scooters across several lines (Mix, MixPro, Navbow, Navbow+, VAPOR, VAPOR Pro, Swii), a robotic pool cleaner (BN/BN Pro), a waterproof phone case (H1/H1+), and related accessories, sold directly and through retailers including Amazon, Costco and West Marine.
Pricing
On 30 Oct 2026, prices on store.sublue.com ranged from about $279 for accessories to $4,099 for flagship scooter models, with mid-range scooters commonly priced from $349 to $999.
Returns and warranty
Sublue offers a 30-day return on products that are unused, unopened and in original packaging, but the refund is reduced by payment-processing fees (starting at 2.5%) and, for non-USD orders, currency-conversion fees (starting at 1.5%). If the box has been opened but the product is unused, a 10-50% restocking and refurbishment fee applies instead, with the exact amount determined by Sublue's own inspection. A used product without a confirmed quality issue is not eligible for return at all. Warranty terms are specific by product: Mix, MixPro, Navbow, Navbow+, Swii, Tini and Hagul EZ scooters get 12 months on body, motion system, battery and charger; the VAPOR line gets 24 months on its main unit and motor (12 months on battery/charger); the BN/BN Pro pool cleaner gets 36 months on non-consumable device parts. A regional service fee of up to 20% of the order price may apply for warranty repairs in certain regions, and replacement products do not restart or extend the original warranty period.
The Mix scooter battery recall
On 13 March 2025, the U.S. Consumer Product Safety Commission issued recall #25-169 for black lithium-ion replacement batteries sold for Sublue Mix underwater scooters (arctic white, space blue and aqua blue units sold between June 2018 and February 2025, roughly 40,370 units), because the batteries can overheat and ignite, posing a fire hazard. The CPSC notice records 161 reports of thermal or swelling incidents, including eight reports of fire, one reported injury, and over $651,000 in reported property damage. Gray batteries are not affected. Sublue is offering a free gray replacement battery through a collection-kit process, and publishes its own recall notice directly in its site navigation under Customer Care. If you own, or are considering buying secondhand, a Sublue Mix scooter, check the battery color (black batteries only are affected) before using it, per the CPSC's official notice.
Buying advice
If you are buying or already own a Sublue Mix scooter, check the battery color against the CPSC recall before using it, and contact Sublue for the free gray replacement if it applies to your unit. For a new purchase of any model, keep the box unopened if there is a realistic chance you will return it, since opening it (even without use) triggers a 10-50% restocking fee, and plan for the refund to be reduced by payment and currency-conversion fees even on an unopened return.

How this review was put together
This is a desk-research review. We have not purchased or used a Sublue scooter. Prices and policies come from store.sublue.com, checked 30 Oct 2026. The battery recall section is based directly on the U.S. Consumer Product Safety Commission's official recall notice (#25-169), not a secondary summary, and we report only the figures stated in that notice. We wrote our own text. The image is our own screenshot of a public Sublue page, taken on 30 Oct 2026 and shown for review and commentary; the content and branding belong to Sublue, and we will remove it if asked. We did not review the brand's affiliate programme terms.
