Will I need to pay import duties or taxes on delivery?
Orders to supported destinations include complimentary delivery. Import duties and taxes are included except for Norway. For deliveries to Norway, customs clearance and any applicable import duties and taxes are the recipient’s responsibility.
Is the packaging discreet?
Yes. Orders are shipped in plain outer packaging with no F-Machine branding or product description identifying the contents.
Does TREMBLR require assembly?
No tools or mechanical assembly are required. Connect the Receiver Hose between the main unit and receiver, then prepare the selected receiver for use. Follow the included manual for setup and cleaning.
Can I use TREMBLR without the app?
Yes. TREMBLR can be controlled with the included wireless remote without the app. The F-Machine Connect app adds local control and remote interaction.
What receivers and sleeves can I use with TREMBLR?
TREMBLR is designed for use with official F-Machine receivers and matching silicone sleeves. The receiver, sleeve, air path and one-way valve work together as part of the pneumatic system. Third-party receivers, sleeves and masturbators have not been adapted or validated for use with TREMBLR.
What receiver sizes are included with TREMBLR?
TREMBLR includes M, L and XL receivers with matching silicone sleeves.
Which TREMBLR configuration should I choose?
For a first purchase, start with the standard configuration. Add original silicone sleeves if you want replacement consumables on hand. Add the 525 Shorts for a more stable hands-free setup, or the 525 Shorts Pro for rear-zip access and multi-device configurations.
How often should the silicone sleeve be replaced?
The silicone sleeve is a replaceable consumable. Service life varies with frequency of use, cleaning method and storage conditions.
Can I return TREMBLR after it has been opened or used?
For hygiene reasons, TREMBLR is classified as an intimate-use product. Unless there is a quality issue, opened or used items cannot be returned or exchanged. Please confirm the model, packaging, included items and exterior condition before opening.
How long is the warranty?
F-Machine products purchased through authorised channels are covered by a 12-month limited warranty. Damage caused by misuse, unauthorised disassembly, abnormal use or incompatible accessories is not covered.
