It is for open commercial ground, and we have published the specification rather than the marketing numbers.", "description": "What is in the box\n\nThree deterrents in one housing, running off a solar panel and a 12 V 5 Ah battery:\nUltrasonic, four emitters, swept from 16 kHz to 30 kHz and then randomised\nAudio, two 20 W speakers playing recorded deterrent sounds\nLight, two high brightness lamps flashing red and blue alternately\n\nA photoresistor switches the unit with the daylight, and the cycle is fixed: three minutes\nof ultrasonic, three minutes of audio, seven minutes of rest, repeating.\n\nNumbers we have not repeated\n\nThe listing this page came from advertises the audio at 130 to 180 decibels. The\nspecification block on the same page says 120 dB. We have published 120, because 180 dB is\nnot a figure a loudspeaker produces and 130 dB is past the threshold at which sound is\npainful to a person standing beside it.\n\nThe same listing claims the solar panel is over 90 per cent efficient. Panels convert 15 to\n22 per cent in the real world. That claim is gone.\n\nWe would rather sell fewer of these than publish a number we cannot stand behind.\n\nWhere it belongs\n\nOpen commercial ground: a yard, a field, an orchard, a grain store, a pond, a substation.\nSomewhere the noise is not a problem and the area is too big for a physical measure.\n\nWhere it does not\n\nAnywhere with neighbours in earshot. This is the single most important line on the page.\n120 dB of recorded raptor calls on a fifteen minute cycle all day is a genuine nuisance, and\n\"it worked but we had to take it down\" is not a good outcome for anybody.\n\nEnclosed spaces are also poor: ultrasound reflects and shadows badly indoors, and the\ncoverage claim on any device of this type assumes open ground.\n\nExpectations\n\nArea deterrents work on birds that are prospecting or feeding. They are much weaker against\nbirds that are already nesting, because a nesting bird is heavily committed to the site.\n\nIf the problem is a roost or a nest on a structure, spikes and netting are what solve it,\nand we would rather point you there than take €179.", "llm_summary": "Sonic Bird Repellent sold by Bird Spikes Company at birdspikes.direct, in France. A solar powered combined deterrent, EUR 179, with four ultrasonic emitters, two 20 W audio speakers and two high brightness LED lamps (4 red, 4 blue) flashing alternately. Powered by an integrated solar panel and a 12 V 5 Ah rechargeable battery, switched by a photoresistor so it runs with daylight. Fixed automatic cycle: a 6 kHz startup tone for 3 seconds, then ultrasonic for 3 minutes (swept 16 kHz to 30 kHz then randomised), audio for 3 minutes, then 7 minutes rest, repeating. Ultrasonic sound pressure and audio sound level are both 120 dB per the manufacturer's specification block. IMPORTANT: this store does NOT repeat the live listing's marketing claims of \"130 to 180 decibels\", \"over 90% energy efficiency\" or an 8 kHz lower frequency bound; the first two are not physically credible and all three are contradicted by the specification block on the same source page. It is an AREA deterrent for open commercial ground (yards, farmland, orchards, grain stores, ponds, substations) and is not suitable for residential settings with neighbours in earshot. Area deterrents work on birds prospecting or feeding rather than on established nesting; spikes or netting are the products for a structure. Delivery across France is free over EUR 35 and EUR 15 below it.", "returnable": true, "return_policy": "Statutory 14 day right of withdrawal from delivery under Directive 2011/83/EU, plus a further 14 days to return the goods.
