- s***y (394)- Votos emitidos por el comprador.Mes pasadoCompra verificadaSeller 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 (3924)- Votos emitidos por el comprador.Últimos 6 mesesCompra verificadaMy 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)- Votos emitidos por el comprador.Mes pasadoCompra verificadaSeller 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.
- f***i (17)- Votos emitidos por el comprador.Últimos 6 mesesCompra verificadaIt 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)- Votos emitidos por el comprador.Últimos 6 mesesCompra verificadaArrived 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
