Because the plastic is so sturdy (it is soft plastic though)

Only squeaky toy that has not been broken by my dog after a couple hours. This toy is very sturdily built and has lasted months and is still working. Because the plastic is so sturdy (it is soft plastic though), it might be hard to squeak for smaller dogs, but if your dog has strong jaws and rips quickly through squeaky toys from pet stores, this is perfect.

I'm trying it to grow Sugar Baby watermelons and Heart of Gold cantaloupes on.  It's still early days (July) so no fruit yet.  The plastic seems sturdy enough to hold the weight.

Finite, I love the soft material on the outside.  My problem is the quality of the plastic that is used to house my Samsung Tab S2.  I saw black plastic pieces in my bag and I did not know where they were coming from and then I picked up my case and a larger piece fell from it.  I don't abuse the case whatsoever so I don't understand why it is falling apart on me.  This just started to happen within the past few months.  I believe I got a bad one but this review does not detract from the quality and workmanship of the product.

This is so neat!  It is clear plastic, sturdy - not flimsy - and is so handy...plus it looks nice!

This container was very heavy, in the context of plastic  boxes, and sturdy. Much more so than I expected. It stays put even if  one drawer is  pulled out and the container is completely empty, thereby eliminating the accidental overturning of the container and it's contents when one compartment is pulled out to obtain an item. Well worth the inexpensive price.

The plastic is really strong and the cellphone fits tightly in the case. It is well made so you don't see left over material from the molding process.
The color is really bright too, I thought it would be on the pale side but it really stands out.
Have not had the phone take any considerable damage since I got this (definitely not looking forward to getting any) but as soon as I drop it I will report any consequences.

The case itself is quite sturdy. I got it for my young nephew who is in kindergarten. Being a kid, he is pretty clumsy all around. He is your typical 5 year old. So when my mobile plan allowed me a free upgrade, I decided to give him my old iPhone 4s. I did not expect it to last long at all since he is just a kid but figured if I bought a case then that would aid in how long it would last. Right? Well, it sure did! My little rough boy managed to keep the phone for about 9 months before he eventually completely dropped ti in the pool.
So yeah, this case is definitely sturdy. The only thing that I was not a big fan of was the belt clip, I mean I don't think they're so popular anymore and all it really did was take up some space when it could have been just a very nice sleek case that protected greatly.
But other than that, it is a great case!

The plastic is pretty stiff. I find that when working with a gelli plate, a softer material works better.

I was expecting a cheap piece of plastic, which was fine for who I was purchasing it for (my 7 year old daughter).  At the price I figured it was worth it.  When I received the paint palette in the mail today I was very pleasantly surprised to find that it is made of very sturdy plastic and will last a good, long time.  This palette is sturdy enough for repeated washings.  I doubt she will ever break it.  If you have time to wait for this to ship from China it is well worth the wait!

Better built than the inexpensive price would indicate!  It is very sturdy!

I like that you can secure it anywhere, but do not like that it is plastic .  I'm afraid that if some one wanted it they could break the plastic easily.

I love how sturdy this case is. The plastic locks together well and the hard rubber on the outside fits perfect. My only complaint is that the design has started to rub off a little on the edges and the back.

I bought this for a family member, whom loves it. I like that it appears as a hard plastic, but is in fact soft. It looks as though it will hold the child securely and allow it to strengthen their muscles. Interesting piece. You can also buy other tables for the chair as the child gets older. The thing I liked the most was it was durable construction, easy to clean, and easy to put together.

I wasn't sure at first seeing that it was made with plastic but it works wonderfully. The plastic is thicker so it's more durable than what I first thought I use it every night when I get home from work.

I'm glad I finally purchased this -- in fact, I should have bought this a few years ago!  I knew we really should have one of these because I like to get shoes for my daughter online as our favorite brands aren't always carried in stores around here.  After reading all the reviews for this plastic one and the metal one, I almost paid the $10 more for the metal one.  After all, I didn't want to pay this much and have it snap in half after the first use.  But I have to say, it's a thick plastic -- very sturdy.  And the movable parts are connected with metal, so they move very smoothly.  This doesn't feel like a cheap plastic "toy" or anything like that.  I think the reviewers who said this is cheap plastic are only saying that because they were expecting metal.  I am planning to take good care of this, just in case (put away from small hands immediately after use) but I really don't think it's fragile at all.  Now, should it be priced like it is?  Well, no.  I feel like a price of $30 would be more fair, but it doesn't seem we have another choice.  So I've taken away a star for the price.  But it is a high-quality item, and I'm confident it will help me make better size choices for my daughter's feet.  In fact, on the very first measurement I had an "aha" moment, "Oh!  Your feet are now WIDE!"  So I highly recommend this item for anyone who buys their kids shoes online.  And yes, you can safely save the $10 and get the plastic one.

I was surprised that the mailbox was really sturdy. In the picture it looks like it was made of plastic. The mailbox opens and closes with no problems.
