Did the job, easy to apply.


Very good will purchase again.


Exact same ingredients as Frontline for a fraction of the cost. Easy to apply and packaging very tough, so no accidental damage or puncture occurs.


I used this yesterday and although it's a different brand to my usual spot on it's fine and a good price.


Good product at a great price. Quick delivery.


Good flea treatment & service


The spot on treatment worked well, and was like any other spot on treatment. The treatment worked as expected whilst not being costly.




As Above


This is the same chemical formula as all of the other spot-on treatments now available. This time it was the cheapest so that is why I chose it. They all work in exactly the same way and if used on your pet every eight weeks without fail, from my experience with three dogs, your pet will never have flees. Consequently I have no idea how effective it is if the pet already has flees when it is applied. PREVENTION IS BETTER THAN CURE!
