I ordered these to use with some arnica oil for my shoulder I had so my hands didn't get so greasy. I've only used one of them so far, but it works great, the roller ball rolls easily and dispenses the oil evenly. Absolutely no leakage. I think the bottles are great quality for the price.

These are awesome. Now you can empty tubes of cream into a roll-on bottle. No mess, no fuss.

I use these refillable roll-on bottles for containing and applying a transdermal DMSO-base NSAID solution that I make. They hold a good amount and the large tolerance around the nylon rollerball allows the liquid to flow out and roll on very easily. My only concern is that I have struggled with occasional unintended leakage at the connection between the main container and the roller-ball assembly. There are only a couple of thin plastic threads holding these two parts together, and this joint is independent of the cap/cover threads. I have experienced leakage in two situations: (1) if I even gently shake the liquid (with or without the main cap on), and (2) if I unscrew the main cap and invert the roller assembly, several drops often leak down on the floor, countertop, or somewhere unintended on my skin. The way I have countered this tendency to leak is always to separately tighten the roller-ball assembly to the bottle, both when removing and removing the main cap. I also am becoming less cautious about-overtightening the connections. Despite the #2 plastic walls of the bottle seeming to be rather thin, and the small number of threads holding the rollerball assembly to the main container, I have not experienced tears or cross-threading of the components. I also have NOT and do not believe I ever will, subject these containers to the ultimate travel-test: throwing them in my suitcase without first enclosing them in a ziplock or other more leakproof container.

They work as they should.

I use these to travel and put my deodorants and other products in here, but they leak so I had to get the glass bottles. They're okay for around the house but would not recommend for travel. If you do make sure it's in a ziplock bag so it doesn't ruin the other items around it.

In our continual quest to free ourselves from the non-stop attacks against our bodies via the pharmaceutical industry and sadly, the horrible commercially-made, processed-food industry, this was just one more step in the right direction. We now use only our own natural deodorant concoctions for everyone in our family, which work great and now that we use these roll-on bottles, they apply just as easily as store-bought roll-ons but without the inclusion of microscopic, toxic metals going into our skin, underlying glands, etc. We couldn't be happier with the ease of use in both application and when refilling. Highly recommended.

I finally gathered all my ingredients to make deodorant; magnesium powder, distilled water, essential oils, and one of these roller bottles. Mixed together, close it tight, give it a shake--wait, it's all over my bathroom now! It leaks terribly, I bet it would hold lotion in. But I must argue this is more meant for liquids. I checked a couple and they all leak. I checked a similar roller bottle from a different brand and no leaking, even though the parts looked the same to me. Thank goodness I tested this on my last return day! The bottle shape is unique, not sure what the point is. But it feels cheap overall.

Im so impressed with these roll on containers! I tried using just one and gave it the ultimate test: I carried it in my large purse. Of course I put most other things in zip lock bags, just in case. I filled a second container and now keep it in my car. Still no leakage although its been hot outside. I bought these refillable roll on containers hoping to put my topical pain gel in them, especially since I'm not supposed to touch the gel directly. This is easily my favorite purchase in the last 90 days.

These roller containers are perfect for putting rub A535 and liquid tiger balm in for easy application. I will try these in the spring, as I am thinking of trying them with a tanning bronzer.

Good size, decent material fast shipping

I use this for the fasciablaster oil. I can buy the large bottle and fill my own roller bottles so I don't use too much oil and make a unholy mess in my bathroom. They work well, I bought some for my friend as well.

Used to send sunscreen to school with my kids. So far not leaking and dispensers sunscreen well. You do need to press down firmly as you are screwing the top on to get it to engage

I’m using one bottle to apply castor oil to my oil pack and another one to rub muscle pain gel to my joints. They work perfectly for my needs. I haven’t noticed any leaks yet. But I think they might leak if the liquid is less viscous than castor oil or gel. The quality is not the best though. Time will tell how durable these bottles are. But, so far, I’m good.
