[EX Q]: Unlike other reviews I read before buying , my locks came sealed and with matching codes , nothing really special about the locks besides being reliable and sturdy locks good for use at a gym .
[EX A]: positive

[EX Q]: These bags look they have a sheen and they're very matte/flat. Construction and materials are low-quality. Amazon gave these a high rating so I went with their recommendation. My daughter will probably like them but they're junky. You get what you pay for. I ordered these for my daughter's birthday and was never provided any information except that they would be late due to bad weather. The status continued to say they would be delivered on the 8th before 8 p.m. When I contacted Amazon on the 9th they told me that the products had been lost and they would not be delivered. The status on the items were never updated. I have shopped on Amazon for years and have had this issue a few times. I have lost faith that items will be delivered within the two-day timeframe. Amazon did agree to provide me with next day shipping, which still made the items late.
[EX A]: negative

[EX Q]: Much cheaper to just get this instead of changing for new ones at a third of the price. I'll definitely be going through more than 3 more oil changes, so this was the best move. Didn't notice much performance increase until it was super hot out, my car didn't skip a beat. Keeps engine running cooler
[EX A]:
positive
