I will lead this review with how pleased I am with the seller "jimmy2016". He was very responsive and answered all of my questions, but be sure make contact through the "contact seller" button! We are using this appliance for our new restaurant in New York City. Despite the high density of Chinese bakeries here, finding this item locally has been nothing short of a nightmare. Very few local suppliers carry it and the ones that do offer no warranty and do not even allow returns. One local supplier told me that after we paid, we could plug it in at the store to make sure it works, but even then there are no returns! That's right, even if the item is totally busted, I wouldn't have been able to return it. A search online yielded only one model from a so called "reputable" manufacturer, sold by a "reputable" supplier that costed over $2000! And no, there was no way I was going to roll the dice and buy direct from Asia via AliExpress.Therefore, I was more than thrilled to find this product available on Amazon. Aside from Amazon's A-Z protection, jimmy2016 offers a 7 day return policy and a 1 year warranty that covers parts. Peace of mind means everything in this business. The best part, the item actually shipped from the US! We got it in about a week. Such a pleasant surprise as the listing says it ships from China and it takes 1-2 months to arrive!This is a new seller that we are glad to have taken a chance on. Note to jimmy2016 - change your name to something more official and update your listing to include your return and warranty policy and that it doesn't actually ship from China!So why only 4 stars? Put shortly, the construction screams budget appliance, but we paid a budget price. You're paying for value, not luxury. What's important is that it steams great and our buns come out just the way we need them. The top temp is higher than the other models we looked at (110C on the dial). There is a failsafe on this model - if the water gets too low the heating element turns off. A critical feature, as the heating element will burn out without water. This failsafe is not readily available on other models. The item also has a CE compliance mark - another detail that ought to be in the listing.While the item gets the job done, here is why I didn't give it 5 stars. The item arrived with a few dings, one of the grates was broken and I had a bit of difficulty with the glass partition that goes above the top rack. The glass partition also had a few dings from poor packing, but its still usable. However, as of this morning the seller has told me that replacement parts are on the way. The racks themselves are a bit wobbly and they seem slightly undersized when placed on the railings. After draining the appliance, a little water still remains in the compartment that houses the heating element, so you'd have to vacuum it out or soak it with something if you want it to be completely dry. The instructions included are not written eloquently and it was missing instructions on how to install the glass partition above the rack. In fact it was not immediately clear what the glass was for and it took some inspection to figure it out, though it wasn't difficult. The seller emailed me this part of the manual upon request. I assume the purpose of the glass partition is to collect condensation and keep it away from the lighting element. Moisture does end up in the lighting compartment anyway and only time will tell what the impact will be. The lighting compartment can be opened so you can clean it and the light is elevated above where water would gather so it should be ok. This is why we rely on the CE compliance mark to tell us that the appliance is safe for use.In conclusion, a great value for your money and we are happy we took the chance! A 4 star product that can easily be improved to 5 with a few tweaks by the manufacturer.
