Rated 2 out of 5 by from It's ok I've had this car seat over a year now and only realized when I needed to move my latest child up from the infant seat that this can only be used forward facing. Not very practical and had I known then what I know now about car seats I would not have purchased this.

Rated 3 out of 5 by from Okay seat Bought this seat from Walmart for about $45. Good deal and my son hasn’t complained so it is pretty good. My problem is the 4 plastic clips that hold the bottom of the cushion down never snapped in place and since they don’t snap in place, they scratch my son as he climbs in.

Rated 5 out of 5 by from Great carseat! We've been using this carseat for a few months now my 5 year old daughter has always met height requirements for certain carseats but for weight she didnt. So when she finally was the right weight for a booster seat I was nervous but this carseat put me at ease! She feels safe in it and I know it will keep her safe. So we purchased an additional one for our new vehicle as well. Will continue to use this brand of carseats for my other two kids as well great in price and great in safety!

Rated 2 out of 5 by from Canoe prongs How in the world do you use those plastic canoe prongs??? It doesn't say in the user manual which is anlet down as my husband took apart the car seat to wash and don't know where they go. I'm guessing the clip on to the front fabric???

Rated 5 out of 5 by from Amazing Carseat I have 3 sons and we have been through multiple car seat but these are our favorite out of them all they’re very easy to put together and easy to put in your vehicle they are very easy to change the settings on too to either put the straps up higher or down lower and very easy to loosen or tighten the straps they seem to be very comfortable for my kids and we also love the cup holders they have on both sides we just absolutely love these car seats and definitely recommend

Rated 1 out of 5 by from Cheap, horrible quality The straps twist, it’s extremelt difficult to tighten the latch straps, or to release them. The shoulder straps get twisted on one of the 3 seats we bought every time we put my toddler in. The plastic is thin and the seat has next to no weight to it. It doesn’t feel like it would protect my child in a side impact crash. I won’t be buying from Evenflo ever again.

Rated 5 out of 5 by from Life Saver My son and I were in a severe car accident and although I walked away very bruised and hurt; his Evenflo car seat did its job AMAZINGLY! He had slight whiplash from his straps but his head was protected as was his whole body.
