Can Lidl’s cheap reusable water bottle rival pricier brands?

The stainless steel Ernesto flask is on sale this week for a tempting £3.99

If you’re on the lookout for a reusable water bottle to take with you to the gym, keep in the car or use at work, Lidl is currently selling one for the bargain price of just £3.99.

When it comes to design and style, Lidl’s Ernesto Double Wall Flask reminds us of popular (but pricier) bottles from Chilly’s and S’well. If you’re shopping for a reusable water bottle but don’t want to reach too deep into your wallet, it might catch your eye.

The Ernesto is one of the supermarket’s ‘Middle of Lidl’ special offers this week, available until Thursday 15 August. We’ve got more details below.

We recently tested 20 different reusable water bottles – find out which ones we recommend by reading our guide to the best reusable water bottles for 2019.

Ernesto Flask: what can you expect for £3.99?

Lidl’s budget bottle is made from stainless steel and uses a double-walled body that aims to keep your drinks hot or cold for longer. It’s protected with a ‘leak-proof’ silicone seal and holds 500ml of liquid.

A handy carry strap attached to this reusable water bottle makes it well-suited to outdoor adventures. If you’re convinced by the Ernesto Flask, you can grab one in white, silver or blue.

With reusable water bottles typically costing between £10 and £35, the Ernesto could be a real bargain. Plus, you’ll save a tidy sum when you’re not buying bottled water on a daily basis.

Reusable water bottles in our test lab

We haven’t tested the Lidl Ernesto reusable water bottle in our lab, but we have gone hands-on with plenty of alternatives. For every reusable water bottle in our test, we asked a panel of users to answer the questions that matter the most:

  • How easy is the bottle to drink out of? While some bottles have a twist cap, others use a bite valve.
  • How comfortable is the bottle to hold? Our testing uncovered a number of bottles that will slip from your hand far too easily.
  • How easy is the bottle to dismantle and hand clean? Reusable water bottles can be tricky to clean, especially if there are gaps in the lid where grime can build up.

We can’t fault the build quality on our highest-scoring reusable water bottle. Not only does it feel great in the hand, but the lid is easy to unscrew. It’s not all good news, though – our lowest-scoring reusable water bottle gives off an unpleasant plastic taste. The lid is also a pain, with crevices in the lid proving tricky to clean.

What about hot drinks?

If you refuse to tackle your morning commute without a hot drink in your hand, have a peek at our list of the best reusable coffee cups and travel mugs. With the environmental impact of single-use disposable cups in mind, we’ve rounded up the best options for your budget.

Making up our list of competitors are cups from Caffè Nero, Starbucks, Waitrose and other big-name brands. We’ve rated all of them on how easy they are to clean and how well they will hold up if you’re using them every day.
