Does the job
We've been using these wipes for several years now, but more often in the past 3 years going through about 4 containers every 3 months for our 2 dogs (use for cleaning paws and bottoms.) The price is great and with regular use, we haven't noticed any irritation to their bottoms.
While I do find them very convenient, there are just 2 things that Petkin can improve on. First, the wipes aren't very moist when you receive them, though they are plastic wrapped on arrival. I often find myself having to wet the wipes with tap water to get them moist enough as to not feel like I'm rubbing a dry wipe on my dogs. Second, the wipes aren't layered so that when you pull one wipe out, the second lifts to make it easy. Unlike baby wipes, you have to find the edge of the wipe yourself which sometimes can get a little tedious. Other than that, we still go back to these wipes as they are reasonably priced for the amount of wipes we require for our two dogs.
As far as PetGuys.com, the customer service is amazing. Fortunately, we live close by to the company so with standard shipping, our wipes came in the following day after shipment.
