Is the Cold1 50oz desktop stainless steel mug worth buying?
I purchased the Reduce Cold1 50oz Desktop Stainless Steel Mug from Costco Canada for 9.99 plus tax. I had seen it online and wanted to see if the hype was real. My goal was to find a large capacity tumbler that would keep my drinks at the right temperature while I work at my desk or relax at home. The mug is marketed for keeping drinks cold rather than hot, so I was curious to test both. Here is my detailed review after using it daily.

Can the Cold1 50oz mug keep drinks hot?
The Reduce Cold1 mug is not advertised for hot beverages and in my experience it is not suitable if your priority is long lasting heat retention. I filled it with boiling water to test it and although the water started out very hot it cooled to a drinkable but not piping hot temperature after a few long hours – not instantly. It might be fine for sipping warm tea while working at your desk but it will not keep coffee or tea hot for hours the way a vacuum insulated travel mug would. If you need a mug for hot drinks I would recommend choosing one specifically designed for heat retention.
How long can the Reduce Cold1 mug keep drinks cold?
This is where the Reduce Cold1 mug really works well. I filled it with ice water in the morning and by the afternoon there was still plenty of ice left and the water was as cold as when I poured it. In fact it stayed cold far longer than I ever needed because I usually finish my drink well before the temperature changes. If you fill it with cold water or any chilled beverage you can expect it to remain refreshing for many hours which makes it perfect for long workdays, workouts or outdoor use.
What drinking options does the Reduce Cold1 mug offer?
The lid design offers three distinct ways to drink. You can sip from the smaller spout, drink directly from the larger opening for bigger gulps, or use the included straw for a more casual drink experience. Personally I prefer not to use the straw and in fact I threw mine away. Without the straw I keep the straw opening closed so I only drink from the main spout. This makes it easier to avoid spills while still being able to enjoy the drink at my own pace.
Is the Reduce Cold1 mug leak proof?
Unfortunately the Reduce Cold1 mug is not leak proof. Even when the lid is fully secured and the seals are in place water can escape if the mug is tilted or placed on its side. I tested this by carrying it as if I were holding a purse and water dripped out almost immediately. For this reason I recommend using it on a desk, countertop, or in a cup holder where it remains upright (it’s actually too big for a standard cup holder). If you need something you can toss in a bag without worrying about spills this is not the right choice.
How easy is it to clean the Reduce Cold1 mug?
Cleaning this mug is very straightforward. The lid components come apart easily and the gasket and both small seals for the mouth and straw openings can be removed for thorough washing. I find this especially important because it prevents any residue or buildup from collecting in hidden areas. A quick wash with warm soapy water leaves the entire mug clean and fresh. The wide mouth also makes it easy to reach inside with a sponge.
What are the design features of the Reduce Cold1 mug?
The mug has an appealing design with a modern shape that looks good on a desk. The large 50oz capacity means I do not have to refill it often which is ideal for staying hydrated. One of my favourite details is the rubber stopper on the base. This prevents the mug from sliding around on smooth surfaces and also keeps it from making a loud clanking sound when placed on a table. The handle is comfortable to hold despite the large size and the stainless steel body feels durable.
Should I buy the Reduce Cold1 mug?
This mug is best for anyone who drinks a lot of water throughout the day and wants it to stay cold without constant refills. It is well suited for home offices, desks, kitchen counters, or outdoor seating areas where it can stay upright. It is also a great choice for those who want something easy to clean and with a high capacity. However if you need a mug for coffee or tea that will stay hot for hours or if you require something completely leak proof this is not the right option.

Final verdict – is the Cold1 50 oz mug worth it?
For under ten dollars at Costco Canada, the Cold1 50 oz desktop stainless steel mug is a remarkable value if your main goal is keeping drinks cold and staying hydrated. Here’s how the product stacks up against Reduce’s claims:
What it delivers in real use:
- Keeps water cold for hours, often longer than I ever needed.
- The 3-in-1 lid really does let you sip, gulp, or use a straw.
- Easy to clean: the lid unscrews and all rubber seals and gaskets come apart.
- The rubber base (soft sit) is great for no sliding or loud clanks when you place it down.
Where it falls short:
- It doesn’t perform well with hot beverages
- Most importantly, it is not leak-proof. Water will leak if tilted or carried in a bag, even with all openings closed (and all seals are cleaned and properly placed)
Compare this to Reduce’s marketing claims:
- It does keep drinks cold and has a large capacity.
- The 3-in-1 lid, measurement markings, soft sit base, and dishwasher safety all perform as advertised.
- Long-lasting cold retention.
- And though Reduce mentions a “spill-resistant lid,” it clearly is not leak-proof when mishandled or tipped.
Overall assessment
If you need a stylish, solid-feeling desktop mug to keep cold drinks refreshing for hours, the Reduce Cold1 50 oz mug is a fantastic buy under $10. It is super valuable with its thoughtful lid options, easy cleaning, and stable base. But if you require true leak-proof performance or want a hot beverage companion, it’s best to look elsewhere.
