"Return was painless"
I wasn’t totally sure how the return would go, but it was easier than I expected. I sent it back and got my refund quickly, so no complaints from me

"A brand I actually feel good buying from"
I’ve been using Seresto for my dog for a while, i just feel safe sticking with it. The website is simple to use and feels legit, which matters to me because I don’t want to end up with some random knockoff when it comes to my pet.

I’m cautious about buying pet stuff online, but Seresto makes it easy to feel confident. The info is clear, there aren’t any unnecessary over-the-top claims, and it feels like a real company is behind it. I’d definitely buy from them again.

"In my experience, the collar did…"
In my experience, the collar did seem to help with fleas, but my dog started getting itchy around his neck during the first week. I took it off for a while and then tried it again later. Personally, I’d say it’s worth being cautious and watching your pet closely when you first put it on.

"Pretty much exactly what I hoped for"
I was expecting the instructions to be simple, and they actually were. I got the collar on my dog quickly without having to reread anything or figure it out as I went. No fuss, no confusion, just easy to use

"Relieved it wasn’t a fake"
I’ll be honest, I was stressed about ordering a Seresto collar online because there are way too many horror stories about fake ones floating around. Like, why is this even something people have to worry about? Thankfully, mine showed up in a sealed Bayer/Elanco box with the correct codes, and my dog has been totally fine using it. Shipping took a few days, which was a little annoying, but nothing major. I’m just glad I went through the official site and didn’t end up dealing with some sketchy knockoff.

"I was a little nervous this collar was..."
I was a little nervous this collar was going to have that weird chemical smell, but nope, it really didn’t.

When I first opened it, there was just a super light scent, and after my dog had it on for a bit, I barely noticed anything at all. It wasn’t sticky or overly perfumed either.

That makes a big difference for me because strong smells in the house drive me crazy. Really happy with it, 5 stars from me 😊

"Nothing fancy, but it showed up fine"
The collar arrived in good condition, and the box wasn’t crushed or beat up, which is more than I can say for some deliveries. Everything was sealed properly and easy enough to open. The outer packaging was plain, almost like they spent the absolute minimum on it, but hey, it did its job. I’d give it 4 stars since it arrived safely and nothing was damaged...

"I bought this from seresto.com for my…"
I bought this from seresto.com for my dog after trying cheaper flea treatments that barely lasted. The collar definitely costs more at first, i feel like someone should apologize for making the good option so expensive upfront. That said, it’s been working for months, so over time it does feel worth it. I also like not having to keep buying drops every few weeks. Shipping was fine too, nothing special, but no issues. Overall, I’m happy with it for the long-term value.

"Collar held up better than I expected"
I got this from seresto.com for my dog, who is usually hard on anything he wears, and so far I’ve been pleasantly surprised by it.
He’s rolled around in the grass, scratched at it, been out in the rain, and it still looks pretty much fine to me. I haven’t done any kind of serious testing or anything, but I haven’t noticed cracking, stretching, or the clasp coming loose.

It’s not the most stylish collar ever, but it feels sturdy enough and hasn’t fallen apart like some cheaper ones I’ve bought before. Can’t say how it’ll hold up long term yet, but for now I’m happy with it.

"Support fixed it, but the order issue was annoying"
My order got messed up somehow, and whoever runs this needs to get that part sorted out. That said, support answered quickly and fixed the issue for me, so I do appreciate that

"Great First Impression"
Right out of the package, this collar made a good impression on me. It was simple, easy to use, and didn’t feel like a hassle at all. I liked that I didn’t have to fuss with it or figure anything complicated out. So far, it’s been exactly what I was hoping for

"One of them held up well"
We had one collar that worked for almost the whole season, which was better than I expected. I remember thinking around mid-season, like, wait, this thing is still going? Not everything we’ve tried has made it that long. It wasn’t perfect forever, but for most of the season it did the job for us.

"Still good after rain"
Dog gets soaked often, and this collar’s been holding up fine. No weird smell after it gets wet, and hasn’t been slipping around either.

"Cleaner than I expected"
I bought the Seresto collar for my dog because I was tired of sprays leaving that weird residue on the couch and everywhere he lays. This has felt so much cleaner, and that was a big relief for me. I haven’t noticed any oily marks on his fur or his bedding so far, which makes me feel a lot better about using it indoors.
There was a little powdery residue when I first opened it, so I did feel slightly unsure at first, but it wiped off easily. I’m giving it 4 stars because I still found myself checking it constantly the first week, mostly for my own peace of mind.

"It really did keep ticks away"
My dog used to come back with ticks basically every time we walked anywhere near the woods, like on the trail, by the creek, even just sniffing around the tall grass. Since I put the seresto collar on him, I’ve only found one tick and it was already dead. No fleas either, not on his belly, not around his neck, not in his bedding, nothing. I also like that it doesn’t have that strong chemical smell some collars have. So far I’m happy with it.

"seresto.com had the collar size I needed when..."
seresto.com had the collar size I needed when a bunch of other places were sold out, so that was a relief. Ordering was straightforward too, which I appreciate because I don’t really like having to deal with customer service unless I absolutely have to. I took off a star because another item I checked was unavailable for a while, but overall the site has been reliable enough for me.

"Pretty easy site to use"
I’m usually a little unsure with sites like this because some make you dig around forever, but this one was straightforward. The pages loaded fine, and I was able to find the info about the collar without second-guessing where to click next. Checkout was clear too. it’s just nice when a website works the way you expect and doesn’t make the whole thing annoying

"My vet was right, right"
My vet recommended this, so I gave it a try for my dog, and it works great. Like, really really great. I’m glad I listened because my dog seems to be doing so much better with it.

"The order went through without any issues..."
The order went through without any issues, so that part was smooth. I guess I was just a little disappointed because the overall experience felt basic.
