The product was advertised as "Thick".  It is anything but thick.  They crack very easily.  Not happy!

They are as advertised...... But poorly made. They break really easy.

They kept cracking and had a lot of holes in them and I only had them for a month.

Rigid but poor quality. Easily cracked, broken or scratched. Will not order from this company again.

They break very easily, I am not happy with them. I use them in my restaurant and I am always embarrassed when they break. I will be looking for another and better brand.

I was not very fond of these dishes. They chipped and crack very easily. I love the design, but was very disappointed in the quality.

I've had these guards for only 4 months and they are already starting to crack. Very brittle. Would not recommend these to anyone unless you have the Wusthof PRO knives. I reinforced them with duct tape and now they serve a purpose.

I'm not impressed with the quality. These would crack really easy. The lids do not snap on half of the time. Although I bought them to store craft items, I have to point out that my shoe size is 6.5 and there is no way these storage boxes would work as advertised.

I've had these boxes since October 2014 and I've used them for storing polymer clay and other craft items.

These glasses are VERY thin. I am not happy with this purchase. Two were already broken when shipped and no way to return?
I have had other Artland glasses and they were great. but not these. I am expecting to find something else soon as I am quite sure these will all be broken soon. I would NOT buy again
UPDATE: I have 3 weeks and glasses are already cracking

I bought these due to the high reviews. Opened the pack to find both cracked.

They are nice, but they break very easily.
Broke two of them while just putting the drill down on the floor.

We ordered these 5 weeks ago. We were very disappointed when within a few weeks time we started to have to replace them. They are cracking and not useful any longer. In 5 weeks we have already had to replace 4 sets!

Didnt think they were what I paid for them.  They ripped very easily.

doesn't hold up for very long, cracks easily after time.

The glass is very thin and will likely crack easily. They do look cool when filled with a dark liquid.

Good thing it was a 3 pack.  These seem to crack easily.  So far they have all cracked at the corners within the first 48 hours.
