Our aim is to despatch all orders within 2-3 working days, and we generally aim for next day. We are, however, a small team with limited stock levels, so at times of high demand this may rise to 5 working days. We will let you know if your order will take longer than this. Items on ‘back order’ are indicated on websites, as are items that are ‘out of stock’. For ‘out of stock’ items, the PayPal ‘add to cart’ button will generally have been disabled until we have availability. All items are suitably packaged and posted using the appropriate Royal Mail service. Please also check the Contact Us web page for holiday information, as we can't send out orders when we are closed.
As a small business we invariably contact our customers personally to inform you when your order has or will be posted shortly. Once despatched, delivery time frames are, sadly, beyond our control. Most international deliveries are fairly swift. However, we have experienced occassional orders that have taken longer than the time frames outlined on the delivery page. These have invariably been to locations that are slightly paranoid about global security, or just located in the back end of beyond. Please don’t bend our ear about this.
If your item for whatever reason arrives damaged, which rarely happens, please contact us immediately and we will arrange an exchange.
For current delivery charges and available options, and other terms, please see delivery information page.

Customduo and Little Monkey branded products carry a standard 1 year warranty against defects in material and manufacture. If your product or accessories fails to operate to specification during the Warranty period we will arrange for your product to be repaired or at our discretion replaced. This warranty is subject to reasonable wear and tear (in our opinion) and correct use and maintenance of the product as applicable. We will not provide warranty repair / replacement if the problem, in our opinion, resulted use outside the product specification, modifications or alterations, incorrect connection, operation or fitting where applicable, external damage due to accident, impact/ abrasion, poor storage, poor maintenance, use of non approved parts, wear and tear parts. We will always endeavour to keep any costs due to damage to an absolute minimum. You will be liable for the cost of return of goods to you for any non warranty issues.
Customduo modules and other products have a standard 1 year warranty against defects in materials and manufacture. Customduo modules are designed to retrofit into existing products that were never intended to accommodate LED technology are, as a consequence, have been a calculated balance of effective performance and longevity. This said, Customduo products have evolved significantly with advances in technology, and typically provide a very high level of protection against damage. If you have a warranty issue with your Customduo product we will repair, or at our discretion replace it. If your module or product is damaged or out of warranty then we will repair it at minimal cost, where feasible. We will advice you in advance of any costs. No warranty is offered on bargain basement products. On occasion, we may offer new products from other manufacturers, that are complimentary to our product range. A good example might be a Petzl Duo lamp. We cannot provide warranty on such items, and we may refer you to the manufacturer. We are not liable to any damage to other equipments which are products are used in conjunction with. LED specification may vary from that stated on web site, generally because of ongoing product improvement.
Little Monkey caving lamps have a standard 1 year warranty against defects in materials and manufacture. Little Monkey caving lamps are designed with the intention that they survive the best they possibly can in a hostile environment, i.e. caves. As a consequence, they get battered and we appreciate that it is entirely feasible to break things occasionally.
Battery packs are sensitive and subject to damage from misuse, impact, temperature and most significantly water. Although in reality fairly robust, as a consequence of this battery packs are only covered by the standard warranty if defects in materials or manufacture can be demonstrated to our satisfaction. The warranty does not extend to wear and tear components where applicable. This includes the front window, lamp bolts, plugs and connectors, cable leads, switch boot including switch if boot is not correctly maintained (older lamps), o-rings. It also excludes damage to cable glands and threaded holes. While designed to be as waterproof as possible, damage due to water ingression as a consequence of lack of maintenance or misuse is not covered. We will always endeavour to keep the cost implications of any non warranty repair as low as possible, and get you going again as swiftly as possible.
Using li-ion batteries requires a level of care, and is not without risk. Do not use Little Monkey / Customduo products if not able to accept this risk. Take special care to ensure that the lamp cable, battery box leads and battery leads are not damaged, especially when fitting batteries into battery box etc. Never use damaged batteries or battery box / holder with damaged leads. Failure to do so could present a serious safety risk and damage to batteries. Battery box /battery holder cabling is designed to be readily maintainable, and should be replaced if defective. Battery chargers will get warm in operaton. Use with appropriate care, and charge batteries in a fire safe environment and under supervision..
Important - Battery polarity (marked on battery holders) must be strictly observed. Failure to do so could potentially cause short circuit and damage to batteries / risk of fire etc.
To help get all this backside covering into perspective, Customduo modules / products, and Little Monkey Caving lamps continue to sell not only because our products offer market leading performance, reliability and robustness, but because we are passionate about caving and consequently look after our customers.
