User Review: Sea to Summit Delta Insul-Mug
Price Paid: $19.95 NZD
This should be a good product as it ticks all the boxes: It's good size for a decent cuppa (2 cups). It's a stable design that can be put down on uneven ground without tipping over. It's reasonably well insulated and keeps your cuppa hot and your fingers and lips unburnt. It has no unnecessary and therefore redundant handle wasting space in your pack...
However it has one fatal flaw that that's seen it lose its place in my pack. The "leak-proof" sip-through lid has a very poor seal and leaks worse than any other insulated mug I've ever used - it makes even the cheapest budget brands seem good by comparison (and it's certainly doesn't retail at a budget price).
Overall it should be a good product but the very poor seal on the lid has let it down and it fails to live up to it's design brief by dripping almost as much of your beverage down your chin as it allows you to drink.
