Hi, I am looking to buy some waterproof membranes to make a housing for my AudioMoth devices. I have enquired with https://voir.en.alibaba.com/product/60380452525-801219240/e_PTFE_acoustic_membrane_for_speaker_and_mic_IP67_waterproof_sticker.html as suggested by another forum post. It is possible to purchase a small number but the shipping is $25 as I think they are shipped from China (I am in the UK). I have also come across http://www.porellemembranes.co.uk/en/products/porelle-industrial-and-scientific/porelle-acoustic-vents/#contact . They are UK-based so I would avoid the large shipping cost, and they claim that their membranes are better than e-PTFE membranes (like the Voir product) as there is less dB loss. Has anyone used the second product or have any opinion on which would be better? Thanks!

Hi, Please could you let me know when the next GroupGet order will be opened? I want to buy 16+ devices for field work starting in May, do you know whether this is realistic? Also, why is AudioMoth more expensive via LabMaker? Thanks, Catherine
