I am a mother, grandmother and an Early Childhood Care provider for 25+ years.  I have had the opportunity to use and to install many different car seats.  I did not know about the Britax seats until two months ago when I began searching for an easy to use car seat for my grand daughters.  I have arthritus and installation must be easy.     After reading all the reviews and checking out the ease of use at the local store displays, I purchased a used Britax Roundabout from ebay.  I can easily install the seat myself and adjust the fit from grandchild to grandchild.  My grand daughter's love the comfort of the seat as well.  The seat reclines so easily with a simple pull of the bar in front!  I could not believe how easy to use this seat is and how wonderful it fits to each child with the simplest of adjustments. Another added feature is the ability to remove and clean the straps and cover. You can purchase additional cover sets from BRITAXUSA.com (often cheaper than sold on ebay).  I highly recommend this car seat to all the children  I provide care for.  I am in the process of purchasing Britax Car Seats for my grand daughter's birthdays to have in their family vehicles.  You will not be disappointed with the Britax seats I assure you!
