Should you buy it?
What we like
- Under $13 - genuinely the lowest-risk entry point in the whole category
- Usually bundled with a starter set of essential oils, so there's nothing else to buy on night one
- Cycling LED color modes double as a dim night-light, and they can be switched off for a fully dark room
- Waterless auto-off shuts it down when the tank runs dry, so it's safe to leave running as you fall asleep
- Small footprint fits a crowded nightstand where a 500ml unit wouldn't
What to know before buying
- Modest tank means it won't run a full night - expect it to stop misting well before morning
- Bundled oils are entry-grade blends, not therapeutic single-origin oils; enthusiasts will replace them fast
- Budget build and pump - at this price the plastic and internals feel their cost, and longevity is the gamble you're taking

Frequently asked questions
GuruNanda vs URPOWER diffuser?
Both are budget picks, but they win on different things. GuruNanda's edge is the oil bundle - you're often getting the diffuser plus starter oils for around the price URPOWER charges for the unit alone, which makes it the better true first purchase. URPOWER is the more proven workhorse with a slightly more established track record for lasting. Pick GuruNanda if you have zero oils and want the cheapest complete starter kit; pick URPOWER if you already own oils and just want a dependable cheap misting box.
Will it run all night?
No - and that's the honest limit of this unit. The tank is small-to-mid, so it mists for a chunk of the evening and then auto-offs when dry, typically before you wake. If your goal is scent from bedtime clean through morning, you want a 500ml tank; look at ASAKUKI instead. GuruNanda is built to get you to sleep, not to run past it.
Are the included oils actually any good?
They're fine for finding out if aromatherapy works for you, which is the whole point of buying at this price. They're entry-grade blends - pleasant, usable, but not the single-origin therapeutic oils a hobbyist eventually wants. Think of them as the trial samples that come free with the trial device. If the concept clicks, upgrade the oils first; the diffuser will run them all the same.
Is it too cheap to trust?
It's cheap, and you should set expectations to match - the build and pump feel their price, and this isn't the unit you hand down for a decade. But 22,000+ reviews at 4.4 stars means it's not a scam; it's a functioning ultrasonic diffuser that does the core job. Buy it to answer the question 'does this help me sleep?' cheaply. If the answer is yes, graduate to a ceramic piece like Vitruvi or a big-tank all-nighter.
