The company is terrible to work with. If you decide to purchase be very cautious with the ordering process. After you place the initial order at least a half a dozen pop-ups try to sell upsell you on other products and services or additional units to your order. There is no opportunity to confirm your order and once you've made your order, your account will be charged even if it is not correct. If you contact them with a problem, they are very evasive and not at all helpful. Their practices are deceptive and manipulative.
