I agree with the other review, these chips are not for a sore mouth or tender gums. The chips are very hard and the taste is delightful if you enjoy the salt/vinegar combo. Unfortunately, every bag I received in that case was over cooked! They were very dark and only a few golden brown chips in each bag. They definitely need to improve that!

I love Cherrybrook Kitchen and have tried almost all of their products. I was excited to try the Ready to Spread frosting, as I do not usually keep the needed ingredients on hand for their box frosting. I am not a picky eater, especially if the item contains sugar... but this was horrible! The consistency is absolutely nothing like regular canned frosting. It is not light and fluffy. It is very gooey. I cannot even imagine trying to spread it on a cake - it would rip it to pieces because it is so thick and gooey. I did not even try it on a cake, because the taste and texture were so off-putting. Seriously, do not waste your money!

Picked one up to use with a laptop running Windows 7 Home Premium. The computer saw the item, but said it needed troubleshooting. Nothing worked. After researching online, I found that many people had run into this problem. Apparently, the firmware is not compatible with Windows 7; it's supposedly been corrected in newer runs, but there's no way to tell if the one you're purchasing is newer or not. I tried contacting Blue, twice, hoping to get a firmware update, or check into exchanging it, but never got a response from both attempts, so I finally just had to return it.
