We use these Warmer pumps for our hot stopping in our yogurt store. Customers love the ease of using them. The only recommendation I would have is that you will need a tray to catch the reminse of the topping. Keeps items warm all day long.

I bought this 3.5 qt. warmer to keep my handmade chocolate fudge topping hot. The pump system works good and helps graduate quantity as well.


Love this warmer! It’s sleek and very professional looking for my bakery. It works very well and doesn’t get clogged with the fudge or the caramel that I use it for.


We attempted to use the pot for our hot fudge in our ice cream business. We had previously purchased an Avantco pot, however we were using a spoon to ladle the fudge across and it was extremely messy and took a while to heat the fudge. This pot heats up quickly and maintains the temperature wonderfully. However, the pump does not seem to work on our hot fudge. We took the pump apart, cleaned it good and placed it is a bowl of water and after many, many pumps to prime the pump, it finally pumped the water so we placed it back in the fudge and attempted once again to prime it, however, after many, many, many pumps, it still would not dispense the hot fudge. We are extremely disappointed.

This warmer doesn't have an on/off switch and turning it all the way to 0 doesn't complete stop the heat, so you have to unplug it when not in use. We sent it back and upgraded to the RWLL35, which has a switch.


This product is very good quality. Size is very good. Look is very good. I love this product. Thank you so much for fast shipping.

from Low Price Supply Inc on

Purchased this item a couple months ago and its been used a half dozens times so far at parties. Warms up quickly and is very easy to clean. Well worth the money, quality product. Would definitely recommend.


My only complaint with this item was that it does not have the exact temp displayed on the outside. Heated quickly and maintained temp. Well made and arrived quickly!


Heats our hot fudge up fast, space saving, and works great, seems well built, not like our last one, used in a high volume ice cream stand


I have dreamed of having one of these for years and so far it sort of feels like a nightmare. We use in our concessions stand for fundraising and many times a night the pump does not “bounce back”. It gets stuck in the down position and it’s hard to deal with when it’s busy and the rest of the unit is hot. It is also hard to thoroughly clean the unit. I’m very disappointed that I spent the money for this unit and I have not had one day of smooth operation.

Not a good unit. Worked ok while it lasted, inconsistent temps, would burn fudge easily. Eventually water well corroded out in under a year and a half. If this is used daily, spend the money once on a better unit rather than twice on this piece of garbage.

Takes too long to warm up, and the pump does not work well. I would not recommend this item, pay more and get a better one

This is a very handy device to have in your kitchen. We use this to make candy apples in the fall and nachos the rest of the year.

Does what it supposed to do. Spout has a little bit of an outward angle so it doesn't go straight down, but it still works fine. Temp settings are actually power output so it takes some figuring out to get desired temperature.


We purchased two just to have a back up but so far we haven't needed this. It regulates the chocolate sauce temperature very well and is easy to just pop the can of chocolate in there.

from Courtney LLC on

This cheese warmer is very good. I use this multiple times a day. It heats up very well. The pump is nice and also smooth.

Product itself is very nice looking but does not work as the advertisement leads you to believe. If you are opening #10 cans of whatever and dropping them in the warmer, it's great. If you want to do anything else, don't buy it. The advertisement says that it accepts both #10 cans AND 3.5 quart inserts. We purchased this pump warmer along with a 3.5 quart insert. When it arrived, we set it up, made a batch of homemade cheese sauce, filled the insert, dropped it in the warmer and got a huge surprise when we tried to put the lid on the warmer. The lid and pump will not fit when using an insert. We double checked the advertisement and the product literature. We couldn't find anything stating that YOU CANNOT USE THE LID AND PUMP with an insert. We had an empty #10 can from some ketchup that we washed and tested. The lid and pump work great with a #10 can. The 3.5 quart insert easily fits in the warmer without issue. You need to use a different kind of lid and spoon. A BIG DISAPPOINTMENT because we purchased this product specifically for the pump more buying a soup warmer instead. Read Less Read More
