Mity rain Accessories Set for Stanley Cup

The Verdict

If you own a Stanley Cup, you already know the deal: the cup itself is great, but the accessories are where the experience lives or dies. The Mity rain Accessories Set is trying to be your one-stop upgrade kit, and at 4.3 stars across 215 ratings, it’s clearly landing with most buyers. But is it actually worth your money, or is this just another Amazon accessory grab bag?

Let me be direct: this set solves the three biggest Stanley complaints — straws that float, lids that spill, and handles that dig into your hand. Here’s the breakdown.

What’s actually in the box

The set includes two lid types (a standard slider lid and a straw lid), four straws in varying lengths and widths, two cleaning brushes, a silicone boot for the bottom, and a carry strap with clips. That’s a complete kit, not just a token straw or two. The straws are made from rigid BPA-free plastic — not the flimsy flexible kind that kink and crack. They’re long enough to reach the bottom of both 30oz and 40oz models, which is the single most common complaint with Stanley’s stock straws.

The carry strap is the surprise standout. It’s thick webbing with metal clips that attach to the handle without scratching the powder coat. Buyers consistently mention this in positive reviews. One verified purchaser wrote, “The strap is way more comfortable than carrying the cup by the handle — it distributes the weight better than I expected.”

How it performs in real use

The straw lids fit snugly on both the 30oz and 40oz Quencher models. The slider mechanism is smooth and doesn’t stick, which matters when you’re driving and trying to take a sip. The silicone boot adds grip on slick surfaces and protects the bottom from dents — a real concern given how often these cups get knocked over.

But here’s the honest tradeoff: the lid seal is snug, not watertight. If your cup tips over sideways in a bag, you will get moisture in your bag. It’s not a leak-proof system like a Yeti or a thermos. That’s a genuine limitation, and you should know it before you buy.

The boot has a similar issue. It covers the bottom completely, which means if you leave your cup in a hot car or a damp gym bag, moisture can get trapped between the boot and the cup. You’ll want to remove it occasionally to let everything dry out.

What buyers consistently praise

Looking through the 215 ratings, the dominant theme is value. You’re getting four straws, two lids, a boot, a strap, and brushes for less than the cost of a single Stanley replacement lid. One reviewer summed it up: “I bought this for the straws alone and got everything else as a bonus. The straws actually work — no more fishing for a floating straw.”

The cleaning brushes also get repeated mentions. They’re long enough to reach the bottom of even the 40oz cup, which is something the stock Stanley brushes can’t do.

Where it falls short

Beyond the leak issue, a few buyers reported that the slider lid doesn’t create a perfect seal with the straw opening — there’s a small gap that lets air in. That’s not a dealbreaker for most, but if you’re someone who needs a completely sealed lid for hot drinks, this isn’t it.

The color options are also limited. If you have a custom or limited-edition Stanley colorway, the included accessories may not match. It’s a minor aesthetic issue, but worth noting.

Who should buy this

• The daily commuter: The carry strap and straw lids make this a solid upgrade for car or train use.
• The Stanley collector: If you have multiple cups, this kit covers both sizes without buying two separate accessory sets.
• The practical buyer: If you’re tired of losing straws or buying replacements individually, the bundle math works out.

Skip it if you need a fully leak-proof system for tossing loose in a bag, or if you’re looking for a perfect color match for a specialty cup.

FAQ

Will these straws fit my 24oz Stanley?
No. The set is designed for 30oz and 40oz Quencher models. The 24oz uses a different lid and straw diameter.

Are the lids compatible with the Stanley IceFlow line?
No. These are specifically for the Quencher H2.0 series. IceFlow uses a different thread pattern.

Can I put these in the dishwasher?
The straws and lids are top-rack safe, but the boot and strap should be hand-washed. The silicone boot can warp in the heat.

The Verdict

Buy it if you’re tired of floating straws and want a complete accessory kit that actually fits the two most popular Stanley sizes. It’s a practical, well-made upgrade that addresses the real pain points.

Skip it if you need a leak-proof seal or you’re chasing a specific color match.

Rating: 4.2/5 — It earns its score. Not perfect, but for the price and coverage, it’s one of the better Stanley accessory sets on the market right now.
