It was so easy to assemble - I could do it myself! It was hard and came in two pieces. I can get pretty muddy in my work and ease of cleaning is important. The sleep diary and the scent diary were strokes of genius, giving us insight into our H and hs private frustrations and inner witticisms. I really only needed one but having a backup adapter is not a bad thing especially since I have 2 Android Phones and 2 microphones. If I hear from them will inform. Other that that the rack is solid doesnt wiggle and I have tipped it back with bikes loaded to open the trunk. I researched and read all the reviews and knew I liked the look of this sandal as I live in regular style flip flops year round, at home in Southern California. Little stiff but am sure I will soon wear them in, amazing price for such high quality shoes! Now let me be upfront I use headphones non stop, ha!
