I was first introduced to TePe thru a friend whose dentist gave them to her to clean between her braces. These brushes are wonderful for folks whose teeth are a bit well spaced. The brushes with out a doubt clean and stimulate the gums helping you to have refreshing breath as well as healthy gums. I bought the purple 1.1mm as well as the green 0.8mm and use them both daily as the space between my front teeth and a few of the molars are a bit larger than the rest of the spaces. If your teeth are close together, tight and you can go to your local Walgreens or Walmart and pick up the GUM GO-BETWEENS gum brushes they sell in the toothpaste isle and you are satisfied with those then these brushes are not for you; however if you feel those type brushes are a bit to small (even if you buy the wide) for the in-between space of your teeth then you are in the right place.The down side is that the picks come with only one protector - the little case it goes in when not in use - so I put mine in an empty pill bottle. They fit perfectly and do not get messed up in my luggage or car.Yes! I will buy this product again.Each brush will last about 3-4 days of usage. Product packaging has changed so that only 1 brush in each package of 8 has protective "travel cap" which also adapts to become the extension handle for the interdental brush, to reach teeth farther back in the mouth. Previously, each brush had its own cap/extension handle. Now I must remember not to discard the cap when the brush is used up, because I will need to use it for the remaining 7 brushes in the package. Less hygienic, as well as inconvenient for me, but a cheaper production cost for the manufacturer, which was not passed along to the consumer.This is the second time I have ordered this bundle. Both orders were for 5 Packages of 8. Both orders came with 1 package of 8. The first order was refunded by Amazon, however I do not want a refund, I want the other 4 packages. I was very disappointed that this happened a second time. I chose this option because of its value. I am learning that there is a serious issue somewhere in the order of things. The product itself is good, just not the order that is promisedI've used TePe brushes for several years after my dentist recommended them. The most recent batch of 5 pack I purchased in late 2018 are just not as good as the ones in the past. Aside from only have one cap that you're supposed to save to use with all of the brushes in one packet, the wire end of the brush that fits into the handle doesn't stay anchored--it twists around! Imagine trying to fit the tip of the brush in between teeth while the brush rotates randomly. That's the frustrating experience I've been having. Terrible! I'm so tired of trying to use these inferior brushes--and I have 40 of them to use up. I probably won't be purchasing these again, at least not from Amazon.I ordered this believing I would get 5 pkg of 8 (40 interdental brushes total) as described in description and order email confirmation. What I got in the mail (all the way from UK) was ONLY 1 pkg of 8 interdental brush. 4 pkgs (32 interdental brushes) is MISSING. I wanted to contact Amazon to see if missing pkgs is on the way, but I have trouble finding online on how I can communicate with them on this matter. Don't think I will order anything else that is coming from overseas. I thought it was a mistake on my part by not check item detail description but I am correct in this.Strange that they came with only 1 cover per package and not one cover for each brush ?Twice I have purchased this “5 packs of 8 brushes, 40 brushes total” item, and twice I have received a single pack of 8 brushes. I just want the full 40 brushes advertised, but there seems to be a system error and only 1 pack is sent each time. The product itself is great, and I highly recommend, but they are not worth more than $2 each.I've ordered these twice for my mother. Each time, only one packet of 8 brushes was sent, not five packets. The first time I ordered, we waited a long time, and then there was just the one package. So frustrating. I reordered and the same thing happened, although the one packet arrived more quickly the second time.La calidad de estos cepillos inerdentales me parece excelente, pero las medidas no corresponden a los que habitualmente compro (interprox).En los habituales uso medida 1.1 (color amarillo) y en Tepe he pedido la medida 1.1 (color morado), que resultan ser muy grandes y no los puedo utilizar.Como la calidad me ha gustado mucho, los he vuelto a pedir en la medida de 0.8 (color verde). Ya comentaré más cuando lleguen.
