We use the my buddy lookout doubled with a dogo harness. It works very well especially with the harness. The straps that came with the carseat were had rather heavy metal clips. They were easy to replace. The dogo harness is great, because of the construction you are able to use the adjustable legnth as a nice lead to attatch to a seatbelt or whatever strap or clip the carseat comes with. Make sure you measure properly before making your purchase. GWlittle has a great demo video on their site
