I bought this item hoping to add a cupholder to a flat handled cart. Unfortunately it's really designed for an angled installation, and while I hoped it would work for me, I couldn't find an real photos of the velcro mechanism. So, I'm giving it 4 stars because it would be great if they improved their description and photos. But it would have 5 stars overall for me if that would have been clear, because the product would work well for both large and small cups...especially if those cups had a side rail to rest against.This was just not a good fit for my rollator. I have a rollator that looks like a boomerang. So the sides are slanted. It needs better stabilizing bands than this one can offerWheelchair related products are always marked up to 3 or 4 times the price of baby gear. Yet, the two are generally either the same product or so similar it's laughable. This cup holder is being sold on several sites for wheelchairs for $60 or more dollars, the old difference being it has a hard attachment. In actuality that makes them harder to use not better. I just wanted to point that out. A bit of PSA.Now, I can fit a 12oz can nicely in it, but it also will hold a large cup without dumping it. It doesn't take a 32 oz cup that's clumsy . Although it will tell you not to I have kept hot drinks in it, I guess I'm a rebel. It does keep them relatively warmer. On the other hand it's remarkably good at keeping a drink cold. I live in a hot environment and it will keep an iced drink from melting in the 90 degree heat. I really love the mesh pockets. I can keep my Samsung J7 in one and my keys, lip balm , etc in the other without affecting the way the drink fits. It's hand washable. Yeah that was awesome. I had a iced coffee leak all over it, you can turn it inside out and wash it out with hand soap. It dried overnight. The reason I took off a star ? Where the velcro strap and plastic loop attach I can see it is going to wear over time. Eventually the fabric will tear. I'm not saying tomorrow, but it's not going to last as long as I would like. Part of that may be due to wear it hangs on the leg rest of my chair, but I don't think so. All in all I think it's well worth the price. As a retired Nanny I can see it being a wonderful addition to a stroller handle too.I bought 2 of these for our City Select. They're great, well made sturdy. BUT they only go on the right side of the stroller...you can't put it on the left, because the attachment is sewn on at an angle so if you put it on the left the cup is tipped, making it unusableon that side. Kindof inconvenient. But we make it work to have lots of extra cupholders when out and about with family. You also can't easily put a large tumbler in it because of the width.It's niceAppears to be good quality, however; did not fit my 32 oz water bottle so I had to return.To attach it to my wheelchair for drinks and my iPhone. It doesn’t attach too well. It slides down the crossbar.I thought if this works on strollers, bikes, and wheelchairs, surely it will work on a beach chair. I was wrong. It slants no matter where you try to put it. I finally poked two holes in the top and zip-tied it to my chair. At least I can use it now.Perfect if you have an umberella stroller like a Mclaren, this drink holder just straps on and is perfect for carrying your bottle of water or your child's sippy cup. Would I put a coffee in it? err no! When you have a drink in this holder it tilts and drinks like takeaway coffees would just spill. But I bought it for my sons sippy cup so we are pleased with it and would recommend them for that reason.Bottles fit but not one with handles.. Doesn't stay out n moves around until striped very tight..not bad for the price but not overly amazing..I'm still using mine on my son stroller but maybe was expecting very amazing branded qualityreally bad! I ams o sorry. it is very fluffy, not rigid base…the cup splitting everywhere. I am sorry but it is a very cheap product.I purchased this product to put my little boys beaker in it and it does just that ,it does tilt a little but was perfect for what I wanted it forIdeal.
