The Pandaloo glass cup with lid and straw is a 20-ounce tumbler designed for cold drinks like iced coffee, smoothies, or water. It comes with a bamboo lid, a plastic on-the-go lid, and a reusable straw. The version tested here is the Black Saphir color, which gives the glass a dark, almost smoky tint. This review is based on using the cup for about three weeks, primarily for iced coffee at home and during short commutes.
One of the first things you notice is the weight. At 20 ounces, the glass is substantial but not overly heavy—about what you’d expect from a double-walled tumbler. The borosilicate glass feels sturdy, and the double-wall construction does help keep drinks cold for a while, though it’s not vacuum-insulated like a stainless steel option. After an hour, the iced coffee was still noticeably cold, but by the two-hour mark, the ice had melted significantly. This is fine for most daily use, but if you need something to keep your drink cold for a full workday, you might want a stainless steel tumbler instead.
The two lids are a highlight. The bamboo lid looks nice and has a silicone gasket that seals fairly well. It’s not fully leakproof—if you tilt the cup too much, water can seep out around the straw hole—but for casual sipping at a desk or table, it works. The plastic on-the-go lid is more practical for travel. It snaps on securely and has a sliding closure that covers the straw opening when not in use. I took this lid on a bumpy bus ride, and it didn’t spill. The straw is a standard straight glass straw, which is easy to clean but can feel a bit fragile. It’s not ideal for smoothies with chunks, as the narrow bore might clog.
A key functional feature is the 20-ounce capacity. It’s a common size for iced coffee from most coffee shops—a standard large iced coffee is often around 20 ounces, so you can order your drink and pour it straight in. The glass is also microwave-safe (without the lids), which is convenient for reheating tea or coffee that’s gone cold, though I wouldn’t recommend putting a cold glass straight into the microwave—let it warm up first to avoid thermal shock. The cup is dishwasher-safe, but the bamboo lid should be hand-washed to prevent cracking or warping.
There are some trade-offs. The glass is not as durable as a stainless steel tumbler. I dropped it from about waist height onto a wooden floor, and it survived, but a drop on tile or concrete would likely break it. The bamboo lid, while attractive, is not as durable as plastic. After a few washes, the wood started to show slight discoloration around the edges. Also, the cup is not insulated enough for very hot drinks—the double wall keeps outside heat away, but the glass itself can get warm if you pour in hot liquid, and the lid isn’t designed for hot beverages. Stick to cold or room-temperature drinks.
Compared to a generic stainless steel tumbler of the same size, the Pandaloo glass cup offers a clearer, more aesthetic experience. You can see the drink inside, which is nice for layered smoothies or colorful iced coffee. Stainless steel is more rugged and retains temperature longer, but glass feels cleaner and doesn’t leave a metallic taste. If you’re someone who values visual appeal and doesn’t mind being a bit more careful, glass is a good choice. If you need something for hiking, gym bags, or rough handling, stick with metal.
Who is this cup for? It’s suitable for home use, office desks, or short trips where you want a stylish, reusable cup for cold drinks. It works well for people who make iced coffee or smoothies at home and want a cup that looks nice on a table. It is not suitable for people who need extreme temperature retention for hours, or for those who frequently drop their cups. It’s also not ideal for hot drinks like tea or coffee. The bamboo lid is a nice touch but adds a maintenance step—if you want something simpler, the plastic lid works fine.
In summary, the Pandaloo 20 oz glass tumbler is a decent option for iced coffee and smoothie drinkers who prefer glass over plastic or stainless steel. It has good features like double-wall insulation, two lids, and a reusable straw. The limitations are its fragility (glass can break) and the need to hand-wash the bamboo lid. It’s not a game-changer, but it does what it promises: holds 20 ounces of cold drink, looks clean, and comes with practical accessories. If you can accept the trade-offs, it’s a solid purchase.
