I will probably buy this VAC Pro as some of my IEMs don't have much "protection" between the drivers and the nozzles, i.e. exposed, so being able to use a tool and a brand that I trust would be quite essential given the prices of the IEMs in my collection.
Just curious, as many here are complaining the price, I just wonder what's a "fair" price for this product in a market of expensive IEM cleaning? In fact is there a fair price in this case as it appears that there isn't a comparable product in the market (cleaning of expensive IEMs, form a vendor that's reputable on product quality and customer service), and in the absence of which there is hardly a "baseline" to do a "mark-to-market" reference vis-a-vis other comparable products in the expensive IEM cleaning product-market segment.
If anyone of of you know other such product alternative I'm glad to hear (pls don't quote me some unknown, unfamiliar products from AliExpress, as I hesitate using these products to clean my Viking Ragnar for example). No offence to these product from AliExpress as I'm certain their price/performance would find their use cases in other product-market segments ..
