Reassuring to use an operator with tracked named-day delivery, exactly what you want when dealing with glass aquariums. Great range, great prices.
Tim England
24hr delivery of a pallet, for a complete marine aquarium. And two days before Christmas. No picking errors, best pricing and then great service with hour slot from UPN Pallet Network. Impressive!
Steve Lesson
Super happy with the tank, no issues whatsoever. The delivery was super fast too. (On the day of the delivery the delivery driver was absolutely amazing btw) Honestly cannot recommend enough 👌
Jonas Wolf
Nice searchable website, plenty of stock, reasonably priced next day delivery, well packaged. Slightly more detail would have been nice as I bought 32mm thinking that was the external diameter but I suspect most people buying these items would know that. :)
Jake
This was actually my first time ordering something from them wasn’t sure on how long I would get it said two days, but literally I ordered it and it came the next day. Packaging was amazing. Didn’t even pay next day delivery and I got the next day If you’re reading my review, give them a try. They don’t disappoint.
AJ
Such a great service. Bought a fish tank Ciano emotions 150 Pro and it's arrived very well packed just 2 days after purchase. After 2 weeks i had an issue with light power supply which has been replaced straight away after I reported that to customer service. They look afyer customers and always replied very quickly if you have any problem. Strongly recommended!!!
Mr NotYour Business
Received my tank on Friday the 13th absolutely perfect driver was really really good dropped it right outside my little doorstep because it was on the path. Very very pleased with my purchase tank is looking absolutely fantastic. Will definitely use you again absolutely brilliant thank you.
