First the cons:

The top should be slightly bigger to allow easier cleaning and for the addition of ice.

The insulation is superb, ice can last days inside (without the addition of water). With water and ice you can easily expect to start the day and end the day with frigid water.

The bottle itself is not special in anyway. I love the color I chose, but I was able to dent the bottle with only my grip. This isn't me bragging, I was about to lose the bottle over the side of our sailboat and grabbed hard to keep it from being lost. I snagged it but I now have a thumb dent where I snagged it. Which leads me to my final con for this water bottle. Why is it so damn slippery, while I appreciate that the paint coating looks really nice color and finish-wise, when wet this bottle is like a slippery fish.

The sanitizing seems to be working so far, I've had no errors yet. My kids and I tested the UV light on local pond water and yes it seemed to have killed everything in our samples, so kudos for actually working!

As I mentioned I love the color and finish on the bottle esthetically. It is truly a great looking water bottle.

So I have mixed feelings about this water bottle so far. It seems to perform the task for which it was purchased to complete. It also seems to be an untested product as I can't for the life of me think that testing wouldn't have shown the above cons that I have quickly found.

Maybe Larq should focus on making replacement UV sanitizing tops for other water bottles? While the idea of a all in one purchase is much more appealing, I quickly see many other water bottles that I'd gladly prefer to use from my kitchen cabinet. Now if Larq only large made a replacement UV sanitizing top for my Nalgene wide mouth bottles?

Overall, I'm really loving the PureVis bottle. I held off reviewing it until I'd spent some time with it (I've had it for about 3 months now and I I use it daily and I'm pretty picky with how my water tastes). I did some home "tests" between the PureVis bottle compared to other double walled vacuum sealed water bottles that don't have the UV light technology to see if there was a difference. In general, I find that most vacuum sealed insulated bottles are better at keeping water tasting fresher and less stale than any plastic/non-insulated bottles. With the PureVis, I have found that it keeps the water tasting fresher for longer and overall the stinky water bottle smell is moderately decreased even compared to other vacuum sealed insulated bottles (without the UV light). That being said, the PureVis, if used about 3-4x/day does eventually accumulate a smell despite the UV light. So I wouldn't say it's completely stink free but its better than those without the UV light. I'm not sure I would say that the water itself "tastes better" purely with the UV light as some people have mentioned. I think a filter is needed for that difference in taste (at least with the tap water in Alberta). I also prefer the insulated version to the non insulated (which I also have) as I like having cool refreshing water and it does make a difference during the day!
Cons: I wish the bottle came in a bigger size (at least 1L which the non-insulated ones come in) as I have to fill it up multiple times a day and I like having cool water to drink. I also want to take it into the backcountry and having a larger capacity would be nice. I'd be ok having a bigger water bottle to carry around as I wouldn't have to fill it up as often. It's also quite slippery and I'm definitely afraid to drop it. I bought the Active Cap add-on in the end, and it helps though I'm afraid to hold it exclusively by the cap for longer periods as other reviewers have mentioned that it eventually stretches and the bottle has fallen out. The non-insulated version, with the silicone sleeve is much easier to carry and not as slippery. I also wish the cap came in other fun colours as it does take away a bit from the nice aesthetic of the bottle.
Customer Service: I had a small issue with the first bottle as the UV light cap was malfunctioning. LARQ was responsive and after sending some pictures and video to demonstrate the defect, they replaced my bottle and I'm happy to say the new ones if working great!
Overall: I love the UV light technology with the vacuum sealed insulated bottle and from my own personal tastes/experience, it does make a difference in keeping the water tasting fresher and less stale for longer. I also like that in a pinch, I can fill it up from a less desirable source and the UV light will do its magic (I've taken it on day hikes in the mountains to try and it's worked well in adventure mode). I'd recommend the Active Loop or the sleeve to help carry it because it is slippery though it would be nice if it actually came with the bottle itself!

I bought the 25oz PureVis. The small size is inconvenient and the trade off for a bigger size is you lose the double wall insulation. You could fill it up to the full 25oz but you won’t be able to use the cap properly unless it’s at bout 20z at the fill line so you don’t get a full bottle of water advertised. I had issues with the cap being stuck in safety mode but I was sent a replacement. It’s only good if you know there’s a good water source but you question it’s cleanliness. While hiking I would recommend the Filtered Bottle. Same for if you’re using tap water at home. So I quickly lost interest within a week. Mostly use it for bedside water to keep the water clean and last longer or just refilling at a water fountain. Other than that I use other refillable water bottles as my go-to daily use. Ones with a larger capacity and double walled

I’ll give it a 5 star for the what it’s intended for. But my only complaint would be that one for how expensive these bottles are y’all could use better material. I’ve barely bumped these things and has left massive dents and scratches on it. Makes no sense to charge that amount to have very cheap material.
When I first got my bottles, one of the lights didn’t work, the other was damaged. Customer service was very quick but I had to use my warranty on them immediately. I feel like those should’ve been complimentary. If I can recommend anything, get a sleeve for your bottle and a strap too. They’re very slick and nice looking, I get compliments all the time. But I have to Cottle this thing like a baby because of how cheap the material was.
