Aluminum Alloy Travel Hiking Folding Collapsible Cup

Pros: This is an awesome piece of kit, handy to have attached to your keyring even if you only use it for showing off with. It's handy if you just fancy a drink of water while on the train and there's no cups available or something like that. It doesn't leak like most people would expect it to so all in all it is a pretty good device

Cons: I can't think of any cons, maybe that it can sometimes be a bit stiff when closing back up or hard to get back into the case, but all in all it is a good piece of kit

Other: It doesn't leak like most people would expect it to so all in all it is a pretty good device

Pros: It is definately very handy. with clip, you will never loose such handy cup. It doesnt leak when extended. the height could even be adjusted if you are using it as a sauce cup while cooking outdoor! Ideal for Shots in the Great Outdoors....Not too much tho.. you dont want to miss out inthe outdoors. =)

Cons: with only 70ml.... one could hardly feel satisfied with the drinks.... Good for kids... not really for adults...

Other: if you really need a small cup....

Pros: This cup is exactly what the product description is, a very high quality metal collapsible cup. To put the size in perspective, I bought the larger model (150ml) and the larger cup was closed, I could fit this smaller model completely inside the larger one (so could carry two cups in one). I find this cup more useful--it has more segments so it raises up more (the larger one has only 3 sections) and this one is truly portable where the larger one is almost the size of "why not just carry a regular cup"!

Cons: The keychain is pretty much a joke, it came off right away. But the hole on the cup is solid, so attaching a new keychain (I'd recommend string like a lens cap is attached to a camera) would be easy.

Other: Quality is fantastic.

Pros: It can fold down very small. I can see this product as being useful for hiking with very limited space to carry things.

Cons: You would not use this on your keychain, it is a very loud tin can. I didn't review the specifications first before ordering and assumed that it would be much larger than it is but it is only the size of a shot glass.

Other: I bought 4 and ended up giving 2 away to another couple that we like to camp with. We are going to use them as our "redneck shot glasses" when we go camping.

Pros: its really cool gadget. folds very clean and unfold with no problem. no leaks or anything. works pretty well.

Cons: it only 50 ml... like a shot of vodka... not even for black coffee.. you cant really old it if there's coffee inside cuz it gets hot. make really loud noise... the keychain isn't very good

Other: kinda cool not sure i would buy it if i knew it was so small...not good for coffee. too hot to hold and too low capacity
