I have been a loyal chilly’s customer for a few years, and have been really pleased with my Series 1 water bottles. My partner and I recently purchased identical Series 2 Coffee Cups and have been hugely disappointed. Despite an unnecessarily complex design, the cup leaks when being held whilst walking and trying to drink from it without coffee ending up all down my front is another story … I contacted Chilly’s to complain about the issue and was told two things: 1. The cup isn’t leakproof: understood but why does it leak with drinking? 2. You should allow your drinks to cool down before tightening the lid: how can you sell a product designed to keep drinks hot for 4 hours and then suggest customers should let it cool first? I was then sent a new lid after insisting that there was an issue and the problem remains. Considering this is one of the most expensive insulated coffee cups I’ve come across, I’d urge anyone considering buying one to think again and to go for something cheaper. Chilly’s is a great brand but this edition is not worth the money and in fact makes coffee on the run and more stressful process.
