Review title is Works great, a little hard to attach [SEP] This wonderful product allowed me to continue using my favorite T3 Featherweight blowdryer with my new Xtava Black Orchid diffuser!! I didn't have to buy a new blowdryer! I will admit that I measured the wrong thing when I ordered the SnozzlePro adapter (I measured the base of the concentrator nozzle that came with the blowdryer and not the actual blowdryer nozzle - oops!) My blowdryer is actually a little wider than the measurements given for the SnozzlePro. It was so close, I was determined to make it work! I was able to do it with a little manipulation and a slender tool to give just a little extra stretch to get the SnozzlePro over the end of the blowdryer nozzle (used a tool WITHOUT any sharp edges or points, nothing that could damage the SnozzlePro or the blowdryer). **I did this at my own risk - knowing that I could possibly damage the SnozzlePro or my blowdryer!!** Very gently, I was able to get the SnozzlePro onto my blowdryer. I made sure it was evenly attached all the way around before adding the Xtava Black Orchid diffuser. I attached the diffuser to the SnozzlePro AFTER I put the SnozzlePro on the blowdryer - the opposite of what the instructions advise you to do. (also note that before attaching the SnozzlePro to the blowdryer, I put the diffuser on the SnozzlePro a couple of times to make sure it fit properly and that I would be able to attach it without needing to use the other end of the adapter to make sure it was secure).  After getting everything in place, I'm happy to say that it's very secure and there's nothing that is loose or has any wiggle room whatsoever!! I'm never removing it!! It's there until the dryer kicks the bucket or something breaks! It's working beautifully! It holds very tightly and securely, it hasn't slipped or moved at all since I attached everything!! You can see in the pics how tightly it's holding. I love drying my hair with this diffuser! My hair looks amazing and dries faster than when I used to use a round brush! No more work drying with a round brush! Just using this diffuser and moving it to different sections of my hair, it's easier than ever to dry my hair! Thank you for making this product that allows us to use this wonderful diffuser on other brands of blowdryers! I will be recommending it to everyone who has curly hair!<br /><br />Update - the adapter and diffuser has come off a couple of times and it takes a little bit of work to get it back on because my blow dryer is a tiny bit bigger than the measurements but I can get it back on. I think it came off because I accidentally held it by the adapter or grabbed it by the diffuser. Definitely only hold it by the barrel of the blow dryer (like in my 3rd pic) or the handle for the blow dryer!
