Ex Input:
I have fed my dogs Instinct Raw Boost for years. I have two big dogs, one with digestive issues, and then added a third big dog to my pack, so that brand of food was too expensive when I have to buy a 21lb bag every week or so. Dog Food Advisor gave this 5 stars, so I tried it. My problem dog didn't have any problems at all transitioning to this food, and my Great Pyrenees with allergies has had no issues. I am extremely pleased with this food. I would highly recommend it.

Ex Output:
positive


Ex Input:
Add my two cents to all the negative reviews. I have experienced all the problems listed by others. Lid not secure; rod doesn't align; primers flip in the tray; tilt unit to feed primer into shell holder & the shell falls out. I have a 20 year old RCBS hand primer feeder that has worked like a charm for thousands of reloads. "If it ain't broke, don't fix it." Addendum: it's 13 weeks and no rebate sent. I wrote them and they couldn't care less. Their reply: It's coming, soon???

Ex Output:
negative


Ex Input:
The length is just right to reach anywhere on the back and the variable speeds allow deep tissue to shallow relief. The cordless feature is very convenient and recharges quickly. Certainly no complaints here!

Ex Output:

positive
