Shared Features

The purchase decision between two similar products is normally hard to make because almost all the features of the products are same and it is hard to find out the competitive advantage of one product other the other, thus facilitating the purchase decision. Such competitive advantage normally results from either distinct functionality or visual appeal. Below is a brief writeup which tells the similarities between the Bakrevolver X4 and Bakrevolver X4S:

Finish and Construction: Both the covers have black Matte finish, which looks elegant and has certain visual appeal. Both the covers are made up of Aluminum Slats and carry the Vinyl overlay. The Vinyl overlay gives protection to the Aluminum from weather conditions or harsh external factors.

Usage Simplicity in Design: Both the covers use the same “rollup” principle which is different than “folding” action. The rollup style covers are in general easier to operate because the operator does not have to do large hand movements. In that context, both the covers fold and unfold in a similar fashion. When unfolded, both the covers have smartly designed “slam-latch” to ensure the cover locking over the bed.

No Velcro or Snaps: Both the covers have seamless construction and do not have Velcro or Snaps. This makes the folding and unfolding process smooth. This also ensures flush fit of the cover over truck bed, which is a feature required to prevent the ingress of external contaminants into the truck bed.

Bed Access: Both the covers provide 100% bed access, which is a feature required to access the cargo stored on the truck bed and gives complete flexibility of the truck bed space usage. Both the covers also provide back view provision to the truck driver which is an immensely safe feature during driving in the folded-cover condition.

Weather Seal: Bot the covers Bakrevolver X4 and Bakrevolver X4S tonneau covers, have robust weather seals, due to vinyl overlay over aluminum slats. The vinyl overlay covers the gaps, as required, and decreases the possibility of water or outside contaminants ingress inside the truck bed.

“Bakrevolver X4S” is an improved design over “Bakrevolver X4” and gives some extra benefits and slightly increased cost. The improved features are hard to notice briefly therefore the reviewer has gone deeper down and states the improvements in X4S version as below.

Firstly, the under panels of X4 have “felt” whereas the X4S have rubbery material. This difference does matter if truck undergoes extremes of temperatures in which the “felt” tends to get separated out from the panels creating operation problems. Secondly, the company has made slight improvements of buckling the cover, during folded condition, for X4S. Thirdly, if seating profile matters to you then X4S has lower, or better flushed seating profile as compared to X4.

In the end, it boils down to the user preferences and usage scenario, which would guide the user to make a purchase decision between the two competing products.
