I was interested to circumvent the robber barons of the car rental, the day up to EUR 20 charge for With Cheap booster seats that are there often to buy EUR 15 rent. With two children because the cost booster seats soon more than the rent for the car.
In addition, there are always situations where a portable child seat is very practical (eg child travels with friends with).
So far, I was also very pleased. Of course, the product is not a substitute for a full-fledged child seat with side shields, etc., but one can take just not always.
Unfortunately I had to dispose of both Bubble Bums within the past few weeks, since the glue between the black plastic valve and the surrounding rubber material was crumbly and no longer was airtight. Thus, "deflated" was every few minutes. Striking for me was that both booster seats had exactly the same problem for a similar period. Particularly problematic: in a model of the damage occurred in the middle of holidays without getting chance rapidly replacement, thus our greater daughter had some time driving long unsecured. Thus, a lack of quality but bring in a lot of trouble!
I have the manufacturer via email about the problem you are informed (without requiring replacement as ensuring all gone). Unfortunately, no response came back.
Lack competition from similar products, I will, despite everything ordered two new Bubble Bums.
But it should be every buyer aware that there probably is a product with expiration date and do not rely on it fully possible!
