Tumble-BeeRock Tumbler - Large Tumbler for Adults & Kids - Rotary Machine for Stone, Rock, Metal and Sea Glass - Polishing Machine for Professionals & Hobbyists - Model TB-14, 1X4LB Barrel

The barrel is very robust and the two piece lid remains completely water tight throughout a 30 day tumble. The frame is constructed of high impact plastic that is quite rigid and more than adequate for the purpose. The motor is of high quality and the transformer is quite robust. The roller bars are designed very well and makes for a very smooth tumble. Additionally, the unit comes with a replacement belt. Overall it's a great tumbler and the 4 pound capacity is just so nice. I can tumble more than double the amount of rocks that I had been able to in the past.

This product is just fantastic. I have been using it for well over a month constantly making sea glass and it only takes three days or less to make the glass. It has been running 24/7 all this time with no problems. A great machine for the price. It took a long time to research the one I wanted. Those who had negative comments about this item don't know what they are doing or are not mechanically inclined. This device is simple to use and is a work horse. Would definitely recommend and buy again.

I dove into tumbling with National Geographic. I soon realized it was insufficient for my needs. My next brand was tumble-bee. I haven't had many issues at all; however when i did experience an overheating issue Jennifer & tumble-bee staff were quick to take care of my concerns efficiently and with professionalism. I am a happy customer and looking forward to their future developments!I have since dabbled with a few other tumblers. I do find tumble-bee to br a bit noisier than some others ive seen but the reliability and service makes this brand stand out.I will Bee a happy tumbling returning customer

I ordered two of the double barrel Tumble Bees. They do work great and produce good quality results (check the photo). However, my first one burned out the motor after 3-4 months of constant use. I followed the manual and set it up as indicated and oiled it frequently (once a week at least). My second one is still running after about 3 months.For the price I still think this is a good tumbler to start rock tumbling, but expect to upgrade down the road if you stick with it.

I have had this in constant use since I got it two months ago. I am a complete novice with tumbling and our first batch turned out great. Use and setup was easy, with checks after each grit run I have had no issues. It is a bit noisy but it is a rock tumbler so that should be expected. I am sure at some point I will get a better larger tumbler but this has been great to learn with.

I purchased a Bumble-Bee Rock Tumbler - Large Rock Tumbler for Adults and Kids - Rotary Tumbler for Stone, Rock, Metal and Sea Glass Tumbler Machine - Stone Vibratory Tumbler - Model TB-14, 1X4LB BarrelWithin 5-6 weeks the motor ceased up and the threaded lid attachment is rusted.Not sure if this is fluke or if this machine is a simply poor-quality machine. Sad because initially I liked the larger volume of stone it could tumble.I had to return it for refund.

The media could not be loaded. I've had 6 different types of tumblers, and this Tumble-Bee is definitely the worst. The motor is extremely loud, much louder than any other tumbler, and much louder than the sound of the rocks (which is where most of the sound would typically come from).It also frequently stops working, as shown in the attached video (with the barrel only half full). This is because the machine is poorly constructed, so the axle is at a slight angle, with the timing belt too long as a result. You can ameliorate this by using the knobs to adjust the motor position every week or two, but the problem never actually goes away.The only upside of this tumbler is the large leak-proof barrel, but that isn't so useful when the motor struggles to spin it.

The product is easy to use but you must follow the directions to get amazing results. That means a good cleaning of the barrel and the rocks, a good stiff brush helps here.
