Bests & Worsts Reviews from Amazon

I bought this very same item in Jan 2015 for the price of $14.70. Now buying this again in May 2015 and the price is now $23.24. I thought it was a little high and didn’t back check the old price when I did the order. Today the order came in and I open the box to find this is NOT the same item I was sent just 5 months ago. They are now charging $8.54 more and the boxes are SMALLER. They both say model 3700 but this newer style holds less with less options vs. the older model. The UPC code is off by one number.
