I decided to use smile love because it was affordable and convenient. I read the reviews and most of them were positive except for a few that I figured had made poor impressions or didn't wear their retainers religiously. I was wrong. I'm left with a bite that rocks side to side. Sure my smile is "straighter" but not as nice as they projected. The aligners wouldn't fit correctly, always popping off in the back if the front was set correctly or vis versa. The aligners also caused gum rescission so $2000 and a gum graft later I've started Invisalign $5000 and I am using a real orthodontist. I'm on my second set of Invisalign and can already tell the difference in the quality of the product. Oh, and Smile love ghosted me when I tried to contact them about issues I was having. Told me I should be using the chewies more and that I should pay another $1500 for their finishing kit.
Tl; dr You get what you pay for.
