The Reviews

The Thule Excursion ES Rooftop Cargo Box was reviewed by 24 different customers. It had above average reviews and a lot of positive comments. Out of a possible 5 stars, the 667ES received 4 and a half. Though the product got good reviews overall, it seems that some felt the installation was quite easy while others felt it was a little challenging. The ones that found it easy to install said that it was light weight, yet durable. The directions that come with the package are easy to follow and very thorough. There are also pictures for those that don’t always like to read. This person that found it easy to install had help. Maybe an extra set of hands is all that is needed.

The cargo box does what it says and that is carry a lot of stuff. Several reviewers had admitted packing it to its limit and reported nothing but praise for the product. One reviewer had packed 4 duffle bags. Another had packed 4 regular duffle bags as well, two razor scooters, blankets, a bag of cleaning supplies and a bag of stuff for a pool. That’s a lot of stuff. The locks help to secure everything, especially when the cargo box is fully loaded.

Many didn’t only like the fact that it provided enough space, but it also kept their things dry and secure. There is a little strap inside the box that will allow you to secure things within. One person did mention that there are rubber dots within the box. They are used to cover up the remaining holes. If you forget to install this, you may open the box to find your things soaked. Do not forget this.
