Awesome product. I must buy another soon.

Hi guy's I'm a single chappy living on a small yacht and have used and commend your product thanks.
However I notice the shelf life is limited and it pays to not overtighten the lid as it can become brittle. My reason for writing here is .Would you consider selling a one liter bottle. Perhaps the market for little old me doesn't cater for this.
Thanks again for a wonderful product. Timothy.

Hi Timothy, thank you so much for your thoughtful review and kind words—we’re really glad to hear the product is working well for you! It’s great to know it’s proving useful out on your yacht too.

We appreciate your helpful tips around storage, and thanks as well for the suggestion about a one litre bottle—that’s valuable feedback however at this point in time we aren't in a position to offer the one litre but will definitely keep it in mind for the future.

Thanks again for your support, it truly means a lot to us!

Stop demanding reviews with more than one email.

Fast delivery of product but hate begging for reviews multiple times. Stop it.

Hi Blair,
Thank you for your feedback — we’re glad to hear you were happy with the fast delivery.
We truly appreciate reviews, as they help other customers make informed decisions, but we understand that multiple follow-up emails can be frustrating. Please know that we only send a maximum of two review requests, spaced out intentionally to be respectful of your time. That said, your input is noted, and we're always looking to improve how and when we communicate.
Thanks again for taking the time to share your experience.
Kind regards, the team at DX50 Chlorine Dioxide
