I will never order from smilox.com aka SmileInc again. I ordered "Generic Extra Soft Toothbrush (compare to Nimbus)" and am COMPLETELY disappointed; they are at least medium in firmness and bear NO resemblance to Nimbus whatsoever. I planned to return them, then noticed at the bottom of the packing slip, "All sales are final. No returns or exchanges." This isn't how a legit company operates; it's some kind of sleazy scam operation.
