Thule Sleek

- Seat belts on the blocks are DANGEROUS! While fastening two children, I encountered the problem of the side belts popping out of the slots—they do not lock in any way! In low temperatures and when wearing gloves, this is also very inconvenient. Holding a struggling child while fastening becomes torture for both of us and takes me a lot of time, especially since there is another child running around. The top child sits at an adult shoulder level, and this system creates a high risk of falling for an active toddler. Fastening the child should be quick and convenient at any time of the year because we use this function constantly.
- no hand brake and deceleration. For a stroller with two children, this is a very necessary feature, because even a small hill or ramp accelerates a stroller of such weight very quickly; this issue is also relevant when climbing a hill as you need to take a break.
- the upper and lower blocks have different attachments to the stroller - you cannot swap one block with another (this is relevant if you want to seat children of different genders from time to time and the blocks are of different colors.)
- for the stroller to pass even a low curb, the stroller handle needs to be extended. This is a feature of the center of gravity of strollers with blocks one behind the other.
- block covers are not removable - they cannot be washed.
- the stroller veers to the left on flat surfaces when the wheels are locked.
- when loaded with two children, it creaks and squeaks quite a lot, which worries me a bit, but it seems there is a 2-year warranty.
