Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Best Card in My Wallet!
Having this card from Prime/ Sync has made things so much easier ! I order something & then go to cart & pay with my Prime card, nothing more. I don’t need to worry about theft or further actions or delays. It’s a done deal & I have more time added to make an additional purchase if I need to in case I forget something. I love this card 💞. So easy, I buy more here cause it’s faster, safer, & all in one easy step & Amazon has just about everything there is so why not ? Best card in my wallet !!!

2026 it has saved me
I never wanted a store card only! When I first applied I was bummed that I only got the store card and I thought about canceling it. BUT A lot has changed this year for sure. New grandparents, grocery being so EXPENSIVE and everything in our house as far as electronics needed to be replaced. Very easy to apply for, love the fact that you can apply without getting a hit on your credit and if you want to accept the offer then do so and if you decide that it’s not enough credit then you can decline the offer and no hit to your credit. I will say this, this was the lowest card that I was offered but I chose to get it anyway and within a month I had already received a credit line increase. I also took a trip out of the country and was able to order stuff and have it delivered with no problems. Every time I use it I get cash back and am able to use that on my next order. This is my weekly card for groceries. I definitely can’t wait until it upgrades to the visa, I would definitely get more use out of it. For those who are Amazon shoppers, it’s well worth it. So far so good, Good Choice.
