- s***y (395)- Feedback left by buyer.Past monthVerified purchaseSeller immediately refunded money prior to dispatch when they discovered that the chemical had deteriorated in storage and no longer matched the description for water content. They also ordered new stick and have offered me a discount when it's back in stock. Great customer service and nice to deal with an honest seller!
- s***s (3933)- Feedback left by buyer.Past 6 monthsVerified purchaseMy order was well packaged and as described. Thank you for the extra bottle of Methyl orange. Although I received a £5 discount on shipping for my two separate orders the postage was still excessive ad they arrived in the same parcel. Please review your postage policy for multiple orders. I will buy from ROK again but I will be messaging in advance to ensure the correct postage is applied.
- i***9 (1600)- Feedback left by buyer.Past monthVerified purchaseSeller sent the item in a plain glass bottle. NOT an amber glass bottle as described. They did not mention this swap to me, they only told me when I messaged them that amber bottles had ran out. They should have messaged and confirmed prior to shipping it out, however, they didn't and I had to return it.
- o***b (52)- Feedback left by buyer.Past monthVerified purchaseVery very honest and serious seller. Because of missing package in transport, Deb immediately sent another one and I got even a surplus as a sign of good customer satisfaction. Great seller and please continue like that. Cheers
- f***i (17)- Feedback left by buyer.Past 6 monthsVerified purchaseIt arrived quickly. It looks exactly as described and the price was very fair. It was well packaged and in great condition on arrival. I’m yet to use it as I’m waiting on safety equipment but it looks like a quality product.
- _***n (26)- Feedback left by buyer.Past 6 monthsVerified purchaseArrived very quickly, very well packaged with plenty of bubble wrap and Shredded paper. Box wrapped in plastic wrap. So stayed dry when left inside gate with a very wet day, driver dropped inside gate 6 foot but no damage. Some free samples to give away so others can purchase from ROK, the spare empty botte sent leaks out top where rubber is so no good. Top of big bottle leaked a bit, but very happy,, the negatives are for ROK to correct, happy with items,,Thank You ROK
