You can’t use a North American Waterpik abroad as the pulse machines have to be specialized for European current. The WP300 is the answer to this problem, it is made for the electrical currents abroad. This Waterpik WP300 worked perfect on my European trip. It is compact in size which made it easy to pack. All I needed was my plug adapter for the country I was in and it worked perfect. It is nice and small and light weight but still had all the power necessary to clean.Small, space efficient. Still don't like the water running out of my mouth all over my hand and the wand but it does the trick.The carry case is quite nice and padded. The unit has a small footprint. I use the attachment for pockets and add a capful of listerine to the water after adding the water to the reservoir. I do run water through the reservoir once I've finished a reservoir quantity's of solution. It works great for me.I used to have the big unit and it was really loud. This unit is less noisy. I like the fact the reservoir is easy to clean and it stores upside down on the unit.I would buy it again.The Waterpik WP-300 Traveler comes with a assortment of Waterpik tips, a multi-voltage power supply, and nice travel case.I think the manufacture calling this device a "water flosser" is a little misleading. You may be lead to believe you can use it instead of your normal string flossing program. I personally have found this device is best used in dental hygiene program that includes professional clueing on a six month interval, twice daily brushing, daily regular flossing and finish with a daily power rinse with the WaterpikThe unit is relatively quiet and does not take up much space in the suit case. It is not on the same level as home units but just the thing for on the go.Perfect for traveling both in size and voltage......and best of all: Tops in performance as irrigator/water flosser!! Have been using Waterpik flossers since around 1983- on the rececommendation of my dentist - among the best advice ever!! After adding a daily or more use of Waterpik to my routine brushing & flossing, the health of my teeth and gums improved dramatically!! I have always taken a Waterpik, regardless of size, when traveling--moving to travel size as available, Yes, would highly recommend!!! Thanks to Amazon for having this item available!!Pricey but excellent. Haven't gone to Europe with it yet. Hopefully it will work there.I purchased the water pik for use during long stays in Turkey. I am pleased with how it operates. My only surprise was that it does not come with a lid to cover the water reservoir. That seems a bit unsanitary to me.Purchased this item three years ago, but it was only used for a two week trip to Europe in 2018 and another in 2019. So after about 30 days of cumulative usage, it died. Since the warranty was long expired I disassembled the unit to see if it might be fixable, but apparently the motor had burned out after being used only 2-3 minutes a day for 30 days.At $99 this model is ridiculously overpriced compared to other available models. I have another Waterpik at home that cost half the price of the travel model and I have used that one daily since about 2015. This travel model should be avoided!We have used this for about two years now and we love it. Although I have to plan the space in luggage for it, it's still pretty compact and well worth the space to us. We go on long trips (4-5 weeks), so it's quite a sacrifice not to have a waterpik that long. Although you need a plug adaptor in many places, it operates on 110 and 220 volts automatically (no switches or settings to make). We love ours and we bet you will too.Broke after 2 weeks, was great apart from that!Water flows out of reservoir as seal is not good Very flimsy for the moneyOnce it was determined that this truly was a worldwide use traveller water flosser, it was great. It does actally operate on 100 to 240VAC, just need the correct adapter for the country you are in. Two are supplied with the unit. Compact and comes with it's own padded travelling bag. Highly recommend.La calidad del producto no la he podido valorar dado que no lo llegué a estrenar, pero creo es una de los mejores del mercado.Aconsejo, NO COMPRAR a través de terceros nunca y asegurarse siempre de la inexistencia de costes de reembolso, en mi caso 8€ aprox pues tuve que devolverlo ya que al consultar a mi dentista me aconsejo otro método de limpieza más adecuado para mi.Yo tuve yo la culpa de no leer la letra pequeña, sino, no lo hubiera, adquirido a este proveedor.Muy contento con este irrigador. Es pequeño pero tiene la potencia suficiente. Yo he tenido anteriormente otros dos irrigadores de esta marca y este satisface igualmente mis necesidades de limpieza interdental. Recomiendo la compra. Trae una bolsa de transporte muy útil para viajar con él. El depósito es pequeñito pero se recarga si es necesario en 10 segundos, no es ningún inconveniente. Ocupa poco en el cuarto de baño en comparación con otros más potentes.
