It is not 50ml. It's more like 20-25ml. The space where the water goes has a WARNING label and a line around it that says you can't fill past this line (which according to the measuring cup included, is somewhere between 20-25ml).2. The colour in the photo is inaccurate. It looks like a silver metal, but in fact it's more of a darker "space grey" (see my photo).3. It technically has a light feature, but since most of the product is opaque aside from a silicone ring at the top which is very far from the LED source, the actual button to turn on the light is brighter than the light feature (see my photo). So it's a pointless feature as you almost can't even see the light. Actually the LED buttons are unnecessarily bright in my opinion.Now the good bits:A. Despite its size, it produces a good amount of mist and that 20ish ml actually lasts for several hours. It's perfect for sitting on my desk and fills my small home office with a light pleasant scent.B. It's relatively quiet. It's not silent but the noise is only about as loud as a deep breath out.C. The parts inside the water container appear to be well sealed so no mould has been growing, unlike the other diffuser I have, which has mould growing in between two layers of plastic around the sensor (impossible to clean even with a stiff brush).D. Build: It looks nice and has a subtle appearance that doesn't draw attention. The metal outer shell has a good weight to it, and the edges look well-machined with a subtle bevel that gives it a quality feel.Based on these positives, despite the inaccurate/misleading description, it would have gotten 4 stars if it didn't make a loud BEEP every time you press a button. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/88478059-harmies-40ml-usb-essential-oil-diffuser-portable-aroma-diffuser-cool](https://www.desertcart.in/products/88478059-harmies-40ml-usb-essential-oil-diffuser-portable-aroma-diffuser-cool) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-19*
