Sunvit-D3 Boost Oxygen Cylinder - Pink Grapefruit Portable Oxygen Cylinder for Breathing Up to 200 Uses | Natural O2 Pure Oxygen Can Promotes Free Breathing, Cold, Flu & Revitalizes Lungs - 9L

Firstly, the Amazon page states 98% and the bottle states 95% (Grapefruit for me). FYI.But more importantly, its a complete waste of money.Flavour was remotely reminiscent of a memory of grapefruit...The bottle kinda aims the oxygen at my lower lip instead of centrally towards where my mouth naturally opens, which meant i had to basically yawn to use it which is awkward, but maybe thats me.Litterally no difference in feeling after using for a bit. No alertness, awakeness, nothing. S.O. agreed with me on this.As an experience (which is why i brought it). It was disapointing too. Going in with no expectations i still felt let down. £20 (near enough) for a deep breath i could have taken myself. I could probably have paid someone £19 to eat a £1 grapefruit and fart in my general direction and felt more effect. Or better still, opened the freezer and took a deepbreath. At least then id have felt something even if it was just cold.Do not recommend. For anyone trying this for a laugh, there wont be any. I wish i could say it was an interesting experiance but it wasnt.No stars.

Absolute waste of money. I brought it in the hope it would help me with my breathing whilst recovering from a bad case of flu. There was no benefit it is just a complete and utter con. Seller is laughing; charging customers for a "bogus" product. 😠

Waste of money

No taste. No help. Is there actually anything in the bottle????

It gives me a tiny boost in energy and mental clarity, especially on days when I need a little extra pick-me-up. The pink grapefruit scent is refreshing and adds a nice touch. It’s a great way to quickly refresh and recharge, whether I'm working long hours or just need a bit of extra vitality.BUT its way too expensive. 2-3/5

Item: Sunvit-D3 Boost Oxygen Cylinder - Pink GrapefruitThis bottle of ‘canned air’ arrived with a plastic seal over the mouthpiece. The bottle itself appears to be made from aluminium so is extremely light, with the only weight coming from the bottle itself. I was concerned that this meant that the bottle was empty but then thought about how much a bag of air would weight - not much!The bottle has a trigger as part of the mouthpiece which you press with a finger once the mouthpiece is in place. This releases the oxygen which has a slight grapefruit taste/smell to it.I was hoping that it could help with cluster headaches, as I had heard of some people using these bottles for that purpose, but sadly it hasn’t been effective for me.On the plus side, it does seem to help me to catch my breath a bit faster after heavy exercise, although of course I still end up panting for a while to clear all of the CO2 out of my system.It’s really hard to tell how much of any benefit is real and how much is a placebo as I’m not a scientist, but if you are considering trying a product such as this, then this one is easy to use and pleasant tasting.

Had a chance to review this and thought why not... Well, I'd very much suggest avoiding it. I felt zero benefits from using this - no concentration boost, no extra focus, no easier breathing. It felt like I took a big breath of flavoured air... Which is exactly what I did!Flavour is like someone passed it under a grapefruit for 5 nanoseconds on a conveyor belt. Barely there, horrible.I even used it during asthmatic episodes and while having COVID... No relief or anything of the sort. Nothing short of a scam - avoid! The only thing going for it is that it lasted about ~175 uses, so that matches up.

Not sure what to make out of this Oxygen bottle.It is light - feels like empty which is ok, that how it supposed to be.Have used it few times now (5?) and sadly, the grapefruit taste is now gone.Didn't really make any difference to my breathing. When I used inalers in the past, there was this 'wow' moment when I could feel the difference.I can't feel any with this oxygen boost.From the practical/use point of view - it doesn't fit mouth properly. When covering the mouth with the mouth piece to avoid any 'spillage', the air hits my chin, not my mouth.When I want it to hit my mouth, I have to place in a way there are gaps. Pointless.I think with the price tag of £20.99 it is just waste of money, in my opinion and experience.
