Great for using when making smoothies.I needed a 20oz cup with lid for days I want to take my protein shakes on the road and don't want a re-usable cup sitting in my car baking in the Texas sun and stinking up the place. I read all the reviews on here and thought for the money I would give these a try.. Maybe there were bad batches previously and I noticed that many reviews were not recent in nature. I bought these and used this past weekend and must say, I have no complaints. I tried snapping a lid on these from one end, pushing the entire lid on from the top and NO issues with the cup collapsing. Also, gripping a full cup, I had no issues with the cup collapsing in and the lid popping off. Again, not sure why those other complaints said that, but maybe there were some older cups which did that, but my current ones do not. Also to test the lid, I set the cup on its side while full of protein shake and rolled it around. No leaks, tight lid seal. I also bought some wide tube straws to go with these and no issues getting it thru the lid. Overall, I'm extremely please with these for the cost and purpose. No I dont know if they are BPA free or not, and for the couple times I use these a month, don't really care.This is our first purchase of these cups. The larger straws are an advantage with small children, although the sharp end o the straw may be an issue for kids who like to stab with objects. The straws are colorful and the width makes drinking thick shakes easier. Each straw is individually wrapped, which is a very small inconvenience when making smoothies for three children under four years, but it is also nice that there is no worry about dust or stray flour or anything else getting on the straws. It is a nice thick plastic and the cups do not stick together when taking one. This was a problem with the last brand we used, and this alone is worth buying these cups, lids, and straws again.It is a good price and a good value. If you like to re-use plastic cups (we do sometimes) you can get at least six or seven uses per cup before the plastic wears too thin. We like them.These sets of Clear Cups with Lids and Straws have made my morning routines way easier. The kids always want a breakfast shake in the morning however, take there sweet time drinking it when I'm trying to run out the door and get everyone to school. I bought reusable hard plastic cups with a straw for on the go. After a few days of use and washing, they get this foul smell and don't look as appealing. After buying these cups, now they have there breakfast shakes to go and can dispose them at school. The cups are sturdy and perfect for any cold/normal temp beverage. Do not recommend putting hot drinks in these cups. Have not tried it but I think its common sense to not do.Also, you can wash and reuse if you want to. I'll wash my morning cup out and then use it for my afternoon smoothie and then dispose.I purchased these cups specifically because I am constantly purchasing iced coffee on the go and wanted to start saving money just making them on my own. I picked this particular vendor because of the images and value. It comes with 100 16oz cups with lids. Additionally, this vendor includes 100 multi-colored straws; which by the way, come in three packs and the straws are individually wrapped as well. The straws are medium width and probably work best for smoothies, bubble tea, or frozen drinks. They seem sturdy and work well with the lid. Not at all disappointed.Good quality cups. The straws that come with them are wide ones do smoothies if bubble tea. I didn’t read the description and since that’s not what is pictured I ordered. I then had to go it and buy straws which don’t really work as well in the cup because the tops of the cup are very tight and often this collapses a smaller straw. Still giving them 4 stars cause there’s nothing really wrong with the cups. Taking one star off because the picture doesn’t match the description or the product because of the straws.I got these cups because for 2 reasons. 1- we drink on the go a lot and I wanted something I could slosh my smoothie into on my way out the door, then, could toss and not have to come home and clean after a day in a hot car. 2- the red solo cups are fine, but in the middle of summer when the flies are buzzing it’s nice to have a lid. This also got my son off of his kiddie cups and into something more grown up while offering at least a little spill protection, or minimizing the destruction from a tip over.I enjoyed being able to use this product. These cups with lids eliminated the clean up behind the smaller children.These cups are great. I put smoothies in them and my son cobbles them up. something about having a smoothie in a take away cup makes it more palatable and enticing to a 12 year old. only problem is i am missing a bunch of lids so i had to wash and reuse lids.Love these! Great size, lids stay on tightly. I would caution about the lids, they tend to stick together, which I didn't realise until I was half way through my cups and noticed I didn't have enough lids.These were greatMaking lemonadeI plan on ordering more
